Thieves stole £150-worth of tools from a Fiat Scudo van which was parked in Amble.
The incident happened on Bisley Road, sometime overnight on Tuesday, January 19.
Meanwhile, police are appealing for witnesses after vandals caused £700 of damage to a Volvo saloon overnight last Thursday in Felton. Damage was caused to door panels and tyres.
Anyone with information about either incident should call police on 101.
