CCTV appeal after train grenade threat

Detectives investigating reports of a man threatening to detonate a grenade on a train travelling between Skegness and Nottingham have released a CCTV image of a suspect.
British Transport Police (BTP) said the man produced a grenade from his bag before pulling the pin after he was asked by a guard to stop swearing.
Although the device did not detonate, and the man claimed he was joking, he continued to act in a threatening manner towards other passengers, before leaving the service at Boston, officers said.
Anyone with information about the incident, which happened at about 16:40 BST on Sunday 18 May, is urged to contact BTP.
