Six businesses were broken into on a Flookburgh business park last week.
Cumbria Police tell us the burglaries happened in the early hours of Thursday and Friday morning at the Airfield Approach Business Park near Moor Lane.
Alcohol, tools and cash were stolen on the Thursday.
Much of that was recovered after police chased a Mercedes van seen leaving the scene - it was abandoned in Morecambe.
However, the sixth offence saw £350 in cash and two electric bicycles taken on the Friday.
Detective Constable Tom Pearman, of South Cumbria CID, said: “We believe that this is a targeted crime series and are looking for anyone with information on the two bikes outstanding to get in touch.
“Fortunately we have been able to recover the majority of the items stolen but this does not in any way dilute the seriousness of these offences. Anyone with information on who is responsible is asked to get in touch as your information could prove vital.”
Anyone with information is asked to contact police on 101 and ask to speak to DC 2453 Pearman.
