Police arrested a suspected terrorist and seized explosives and detonators at a railway station in eastern Pakistan on Sunday, an official said.
The 28-year-old man, identified as Mohammed Awais, was carrying 2 kilograms (4.4 pounds) of explosives and other bomb-making material hidden amid clothing in a bag when he was arrested at the main railway station in Lahore, said the city's top police investigator, Chaudhry Shafqaat Ahmed.
Awais is an expert bomb maker and belongs to an outlawed Islamist group, Ahmed said. He would not identify the group or say why Awais may have been carrying explosives.
Westerners as well as Pakistan's Shi'ite Muslim minority have been targeted by bombers.
