Besides the suspension, Thomas was also served with two memos this month by the CPI(M)-led LDF government, citing service rule violations in two books penned by him.
One among them is his bare-all autobiography 'Sravukalkkoppam Neenthumpol' (Swimming Along With Sharks).
The top cop had triggered a row by initiating a probe against high-profile persons, including ministers, politicians and bureaucrats during his tenure as vigilance chief.
"My suspension is a warning to all potential public servants who act against corruption.The message to them (from the government) is very clear...you should tide with corruption," Jacob Thomas told PTI.

"Those who are in power can retaliate against officers in various ways. Suspension is one of such means. But I will continue to blow the whistle on corruption," he said.
Chief Minister Pinarayi Vijayan had last week issued directions for suspension of the officer as the head of the Institute of Management (IMG) in Government under relevant sections of the All India Service Rules as some of his recent remarks had shown the state government in poor light.
He also accused the government of not "properly handling" the situation due to Cyclone Ockhi.
Alleging that all "corrupt forces" are united in the state and are in positions of power, the official had also claimed there was a conscious attempt to silence those who stood against corruption.
In the suspension order, the government pointed out that the statements by Thomas were "certainly inflammatory in nature" and "unwarranted and unbecoming of an officer of his stature".
He said he had been organising programmes to mark the International Anti-Corruption Day for the last four years to raise public awareness on corruption and urge people to fight it.
"This year also I took part in a seminar as part of the day and cautioned people about some possible ways of corruption. My job is to create awareness about corruption. What is wrong in it?" he asked.
During the speech, Thomas had criticised the way in which the Rs 1,400 crore tsunami fund was used for rehabilitation in the state.
Stressing that there are many ways to sabotage a probe into corruption charges, Thomas said it was the government's duty to give necessary protection to public servants who act against corruption.
"Those who act against corruption and expose such wrongdoing in the government system should be protected under the Centre's Whistle Blowers Protection Act," he said.
Interestingly, Thomas, during his about 30 year-long career, had sought protection under the WBP Act three times.
He also sought WBP protection last year as Vigilance chief during investigation of charges against some top bureaucrats.
The IPS officer had earned ire of the ruling CPI(M) after he registered a vigilance case against the then industries minister E P Jayarajan over charges of nepotism, following which he had to resign from the Cabinet.
Chief Secretary K M Abraham and Additional Chief Secretary Tom Jose had lodged a complaint with the chief minister against Thomas after the vigilance department raided their residences over alleged disproportionate assets.
