Mr Roy along with bank employee Anupam Tarafdar, who shared Roy's post, was arrested on October 19, and released on bail yesterday.
According to sources, some of the comments to the post were offensive and attacked a certain police officer. As soon as it came to police's notice, many people were called for questioning. While some of them apologised to the cops, Roy and Tarafdar didn't and were arrested.
Two defamation cases were filed against them -- one by the battery-operated rickshaw drivers association that claimed they were being maligned in their posts and the other by the police. These offences carry jail terms ranging from three months to 10 years.
The two were produced before court and remanded to police custody for two days. On Sunday, a special court granted them bail against a personal bond of Rs 2,000 each. However, the police haven't dropped the charges against them and investigation will continue, a senior officer said.
