A man-hunt is underway following an attempted armed robbery in East Grinstead.

The incident occurred around 9.30 Saturday morning at Stone Quarry post office in Hollands Way.

Believed to be in his early twenties, the suspect walked in and threatened a member of staff with a knife.  He ran off after staff prevented him from climbing behind the counter.

The man is believed to have ridden off on a small-engined motorbike. No one was hurt.

Police have released a description of the offender: a white male, 5’10”, early 20s, of average build and clean shaven. He spoke with a southern accent and was wearing all-black fabric motorcycle clothing and a white crash helmet.
