THREE teenagers have been arrested in connection with an attempted knifepoint robbery.

Two people allegedly approached a 13-year-old boy at the Manor Sports Ground in Broadwater Road, Worthing, between 5.30pm and 6pm on Sunday.

They engaged the boy in a conservation, drew him away from the car park and allegedly threatened him with a knife and tried to steal his backpack.

The boy managed to escape with minor injuries but had to leave his black “Scott” bike at the sports ground and this has not yet been found.

Three boys were stopped nearby and detained by police officers at about 6.45pm.

Anyone who saw the incident or three boys acting suspiciously in the area at the time is asked to call 101.

A 14-year-old boy from Sompting and two 15-year-old boys from Lancing and Worthing were arrested on suspicion of robbery.

They have been released under investigation.
