CrossRiverWatch reported  that FSARS invaded the Lagos bakery of Violet, wife of Jalingo, where they “seized the phones of all staff present and ordered them to show to them Jalingo’s residence”.
On August 23, police transferred  Jalingo to Calabar, the capital of Cross River State in Nigeria's Niger Delta region, according to the Committee to Protect Journalists. Jalingo's transfer to Calabar was allegedly on the request  of Ben Ayade, governor of Cross River State.
Abuja-based online daily Premium Times stated that  Jalingo was, on August 30, charged with treason, terrorism, cultism and public disturbance in a Federal High Court in Abuja, for “working with the #RevolutionNow movement”—founded by detained  human rights activist Omoyele Sowore to protest bad governance in Nigeria— to ”undemocratically’ force the government of Ayade to end through violent means.”
If convicted, Jalingo risks life imprisonment, fine or both.
Politics meet journalism
Cross River State Governor Benedict [Ben] Ayade , is an opposition politician with the Peoples Democratic Party (PDP).
Ayade's greatest headache has been from the African Action Congress (AAC), a political party founded by the #RevolutionNow movement protest leader Omoyele Sowore.
Jalingo, who also doubles as the state chairman  of the AAC, has regularly criticized  Ayade's governance  of Cross Rivers State. Ayade had allegedly threatened that  Jalingo will “face prosecution for misinformation.”
Ayade was re-elected  as for a second term of four years in the February 2019 elections, where he beat his closest rivals from the ruling All Progressives Congress (APC) and Social Democratic Party (SDP).
It is not certain if the AAC fielded a candidate during the governorship elections. The breakdown of the 2019 governorship elections results by the BBC  only showed three parties: Ayade's PDP, the APC and SDP.
On July 17, Jalingo wrote a critical story about an alleged diversion  of 500 million naira (about $1.4 million United States dollars) meant for the establishment of Cross River state Micro-Finance Bank. Jalingo stated that “eight months after the opening of the bank,” Ayade had failed to to release the money meant for the start-up of the state-owned bank:
Governor Ayade will do Cross Riverians a whole lot of good by coming public to tell the people of Cross River State, where the 500 million [Naira] he released for the Cross River State Micro-Finance bank is, because the money is certainly not in that bank.
On August 14, the Cross River State Command of the Nigerian Police invited Jalingo for questioning  on the allegation of “conspiracy to cause unrest and conduct likely to cause a breach of peace”:
This office is investigating a case of conspiracy to cause a breach of peace, reported by Cross River Microfinance Bank, Calabar, in which your name is mentioned. To facilitate our investigation, you are kindly requested to interview the Deputy Commissioner of Police, State Criminal Investigation Department, Calabar, on Monday, 19 August 2019, at [7:00 p.m.] 1400hrs, to state your side of the case.
However, Jalingo was arrested in Lagos on August 22, four days before the scheduled date to honour the police invitation.
‘Criticizing government is now treason’
The arrest and subsequent charge of Jalingo for treason have ignited reactions from Nigerians online.
Ada Campbell, a digital consultant, cut through the murky waters of journalism in Nigeria, where “criticizing [government] is now treason”:
“A Nigerian journalist, Agba Jalingo, who has been in police detention for over a week, over a report about an alleged diversion of N500 million by the Cross River governor, has been charged with treason.”

Writer Gimba Kakanda said that linking Jalingo with Sowore was a diversion because the government “[wasn't] going to win”:
He was arrested for writing that the Cross River state Governor diverted N500M. He sued the police for illegal detention and, knowing they weren’t going to win, they accused him of supporting Sowore — of treason, terrorism, cultism and public disturbance.https://t.co/1h9zS3FWo4

Abdul Mahmud, a lawyer and human rights activist, asks if a charge of treason can be sustained “against a citizen for allegedly planning to topple a governor” under the Nigerian constitution.
FRN v Agba Jalingo.
Lawyers, can the charge of treason be sustained by @policeng  against a citizen for allegedly planning to topple a governor? Is treason a state or federal offence? Is the governor a sovereign or a federal agent?
This country confuses the Great Oracle o!

The “assault against free speech in Nigeria is alarming”, quipped Nafiu:
Agba Jalingo, a journalist, charged for treason for daring to criticize the Cross River State governor
The assault against free speech in Nigeria at the moment is alarming
Any politician who is unwilling to subject himself or herself to public scrutiny has no place in politics

Darlington Edem, chairman of the Association of Cross River Online Journalists, stated that Jalingo's arrest has only shown that  “the media in Cross River State is caged and controlled.”
Similarly, the Lagos-based International Press Centre (IPC) has called for the unconditional release of Jalingo. IPC condemned  “the growing crackdown on freedom of expression” in Nigeria as evident in the frequent “molestation of journalists and the media by security agencies.”
