Someone smashed windows and pilfered from 29 cars in Halethorpe Wednesday night, Baltimore County police said.
One of the cars' owners reported the crime, in the 5700 block of Southwestern Ave., to police around 5:10 p.m.
The vehicles were parked on the street, near but not on the lot of the Halethorpe MARC Station, said Paulette Austrich, a Maryland Transit Administration spokeswoman.
Both county and MTA police are "increasing patrols" in the area, Austrich said.
Authorities are asking anyone who has information in the case to call 410-887-0872.
