Cash was stolen when two vans were broken into in Mildenhall sometime overnight between Thursday and Friday.
A white Ford Transit van had its side window smashed in Peterhouse Close. A small amount of cash was stolen from the cab.
Meanwhile, a Mercedes Sprinter van was broken into in Lark Road, after the offender gained entry by removing a side quarter-light window. The cab was searched but nothing was stolen.
