A man accused of orchestrating bomb attacks in the Indian city of Kanpur was arrested in Britain on Thursday, police said.
The 31-year-old suspect was arrested on suspicion of preparing acts of terrorism, police in the northern Indian state of Uttar Pradesh said in a statement.
He is a resident of the town of Kannur, in the district of Gokul, and is a member of the Indian National Congress party, it added.
Police in the state of Haryana said they were searching for the alleged mastermind of the attacks, who they described as a local resident.
“We are searching for a local man in connection to the terrorist attacks.
He is an associate of the accused, and the operation is being conducted under the Intelligence Bureau,” police chief Ashok Kumar Gupta told AFP news agency.
Police are hunting for the man, who was arrested from his residence in the western state of Rajasthan, according to a statement on Twitter.
India is on high alert following a spate of bomb and gun attacks, mostly targeting Indian and international tourists.
The country is currently in a state of emergency after the November 8 elections.
Police say the man was arrested near a bus stop in the town, and he had a fake passport.
The police statement did not specify whether he was a British national or a Pakistani national.
The man is being questioned by police at a local police station in Kannu, in western Uttar Pradesh state, where he has a wife and three children, the police said in the statement.
