Pensioner foils Brighton post office raid
An elderly man foiled an armed robbery by tussling with a knife-wielding raider.
The 75-year-old managed to grab the robber's crash helmet after he had burst into the Premier Store Post Office, in Widdicombe Way, Brighton.
The offender fled on a moped driven by a second man after the incident on Wednesday.
Three men are being questioned by police. The men, two aged 18 and one 27, were arrested early on Thursday.
Sussex Police said they were also being questioned in connection with two street robberies in Brighton.
The man who intervened has been praised.
Det Con Robin Aspin said: "He is to be applauded for his bravery and his action has given us a very good chance of finding the suspects.
"As they made their escape, the pillion passenger would have stood out because he wasn't wearing a helmet and someone out there will almost certainly be aware if someone they know has returned home without his usual crash helmet."
No-one was injured in the raid.
