FOUR people have been arrested in connection with an armed robbery on Teesside.

Three males, one allegedly brandishing a small silver handgun, and one holding a knife to the shop assistant's throat, stole cash from a shop on Stockton Road, Hartlepool, at about 11pm on Tuesday.

Three men, aged between 17 and 23, and one 23-year-old female, were helping police with their inquiries yesterday.
