FOUR men threw a concrete block through a bike shop window - but were scared off by a passer-by before they managed to steal anything.

Police are appealing for witnesses to the incident, which happened on East Street in Crewkerne at around 2.30am on Thursday, March 25.

One of the offenders was described as around late 20s or early 30s, of medium build and wearing a light-coloured hoody with a hat on and possibly grey jogging bottoms.

The other three all appeared to be wearing dark clothing.

"Four men arrived at the scene in a dark-coloured van and threw a concrete block through the window, before kicking the window several times to gain access to the premises," a spokesperson for Avon and Somerset Police said.

"A passer-by scared the group off and they fled the scene, driving off towards Crewkerne High Street, without stealing anything.

"Their vehicle is described as a dark-coloured large Transit-style van.

"The number plates were covered up, but the covering on the rear plate had slightly come off and we believe the last two letters were UO."
