Police are hunting this distinctive robbery suspect - wearing a nuclear or chemical suit and a gas mask.

The image is one of two released after armed robbers raided the Greensoles Golf Practice Centre in Manston Road, Manston.

Two workers were tied up by at least two offenders armed with a machete and a handgun on the evening of Sunday, July 17.

No-one was injured and no shots were fired, but the robbers fled with the weekend's takings.

Detectives at Margate Police Station have today released the CCTV images and issued a fresh appeal for witnesses.

A patrol car will also be in the area tonight, Saturday and Sunday evenings and Det Insp Nick Greenan, who is heading the investigation, is hoping it will also jog people's memories.

He said: "This week three significant witnesses who had been playing golf on the day of the robbery have been identified and spoken to, having returned to the area.

"We want to speak to people who regularly travel through Manston but perhaps don't live in the area. Because they aren't local they may not have heard about the robbery yet they could have vital information."

The robbers wore distinctive green nuclear, biological, chemical-style protective suits and respirators.

Det Insp Greenan said: "We are still very keen to speak to anyone who was staying at nearby hotels or who used the golf range on Sunday 17 July between 7.30pm and 10pm."

Witnesses should phone Kent Police on 01622 690690 or Kent Crimestoppers anonymously on 0800 555111 quoting crime number EY/11563/11.
