MURWILLUMBAH Truck Centre workers have appealed for help after two men allegedly stole from its retail store twice in one week.

Service manager Adam Bedser said staff of the family business became suspicious after some products were missing after a man entered the store and asked an unusual amount of questions the Tuesday after Anzac Day.

Two days later, he said the man returned with an accomplice and more equipment disappeared.

Equipment worth a total of $3685 was allegedly stolen, most notably several GME 4500 UHF radios, which were worth about $400 each.

Mr Bedser has released CCTV images of the men in hopes of identifying them. Parts manager Steve Maguire said the men seemed to preoccupy staff with questions about their products, before putting products inside their clothing in clear view of the CCTV camera.

He said other businesses as far north as Yatala in Queensland believed they had also been targeted by the same men, who drove a silver-green 2006 model Ford Falcon sedan with partial Queensland registration 144H.

Tweed/Byron LAC Inspector Mick Dempsey confirmed the matters had been reported and were still under investigation.
