A 23-year-old terror suspect was arrested at Burdwan railway station in West Bengal on Monday evening, officials said on Tuesday.
Sources said that Burdwan Police and officials of Government Railway Police (GRP) nabbed the man from the Viswabharati Fast Passenger train based on specific intelligence report.
He was travelling to Labhpur in Birbhum district and boarded the train from Howrah station. Sources added that sleuths followed the man from Howrah.
Senior police officers including superintendent of police (SP) of Burdwan district Kunal Agarwal reached the station.
According to police sources, police and GRP officials interrogated the man throughout Monday night and found that he came from Chennai. They also said that he is fluent in seven to eight languages.
He was brought to the headquarters of Criminal Investigation Department (CID) in Kolkata for further interrogation.
Officials said the National Investigation Agency (NIA) and Intelligence Bureau have been informed about the arrest.
West Bengal was put on high alert after 20 people were killed by a group of terrorists who took foreigners hostages in an upscale cafe in Bangladesh capital Dhaka. Security was tightened on the India-Bangladesh border and all security and intelligence agencies, police and BSF were also put on high alert.
Burdwan district appeared on the terror map in October 2014 when two suspected Jamaat-ul-Mujahideen Bangladesh (JMB) terrorists were killed at a rented house in Khagragarh locality while making IEDs.
The NIA arrested a mechanical engineering student on suspicion of being a terrorist from Durgapur in March this year. Another person, suspected to be Bangladeshi militant, was also arrested from Asansol later.
