POLICE have released an e-fit of a suspect who threatened a man with a needle near a park.
Detectives are hoping the image – drawn up with the help of the victim – will lead them closer to an arrest.
The victim was approached by two men as he walked in the alleyway at the side of Hotham Park, Bognor, at about 3pm.
They spoke to him briefly and as he walked on the pair approached him from behind on bicycles.
One of them produced a needle, demanded the rings from his fingers and also took his rucksack.
They then rode off back down the alleyway towards the subway.
The first suspect, in the e-fit, was in his late 20s, of slim to medium build, and had a tribal pattern tattoo on the bottom of his left forearm and wrist.
He spoke with an Eastern European accent and rode a red mountain bike.
The second male suspect was about 6ft tall, with a muscular broad build with very short cropped brown hair, light brown stubble and tattoos on both forearms.
The robbery happened on August 7. A police spokeswoman said: ‘We hope that by releasing this e-fit of the main offender it will jog someone’s memory.’
