SHERMAN OAKS (CBS) — Authorities are searching for vandals who targeted four businesses Monday night.

Authorities first received a call about a smashed window at Rodeo Realty in the 15300 block of Ventura Boulevard.

A Leeds mattress store, a home furnishing store and a Thai restaurant on Sherman Way were also damaged.

Officers say windows were broken with BBs or marbles fired by a slingshot.

The attacks appear to be random, but the LAPD is investigating similar incidents that took place in Sylmar Monday.
