A KNIFEMAN escaped with cash after a raid on a filling station.

The robber walked into the Total Washington service station in Heworth Road, Washington, Wearside, at 9.15pm on Saturday.

He threatened the sales assistant with a knife, took a small amount of money from the till, and fled outside, where another man was waiting on a dark coloured motorcycle.

The knifeman was about 5ft 10in, in his late 20s, slim, and was wearing a dark green anorak with the hood pulled over his face.

The company is offering a reward of £2,000 for information leading to the arrest and conviction of the raiders.

Anyone with information is asked to contact police on 0191-454 7555, extension 66445.
