An unsolved knifepoint robbery at the Chapel Street Mobil service station will air on Police 10-7 tomorrow night as police continue to search for the man.

Around 8.15pm on October 2, a man entered the service station armed with a knife and began demanding money from the sole attendant at the counter.

CCTV footage of the man police are looking for in relation to the armed robbery.

The attendant handed a quantity of money to the offender, who then walked out the door with it.

In store CCTV footage released by police following the incident has so far come back with little information and police hope Police Ten-7 will generate some leads.

Filming took place at the store on Labour Day following a last minute decision to feature the unsolved robbery in this week's programme. The appeal will air tomorrow at 7.30pm on TV2.

The offender is described as a male Caucasian, in his early 20s, of medium height and medium build. He was dressed in a dark coloured, long sleeve hoodie, with Adidas on the back. He had black jeans, with black and white shoes, and dark coloured beanie and sunglasses.
