An “opportunist thief” struck at 6.45am on Thursday, August 2, when the white Ford Transit van was at the level crossing in Eastern Avenue.
The driver was unaware the theft had taken place until he started to drive away and saw the van’s back doors were not secure.
The missing items are a green Bosch cordless power drill and a Bosch metal detector.
It is believed the thief entered the rear of the van when it was stationary at the level crossing.
Any witness or anyone with information is asked to call 101 quoting serial 272 of 2/8.
