The owners of 11 cars awoke this morning to find their tires had been slashed in Philadelphia's Kensington neighborhood.

The incident is just the latest in a series of attacks by vandals targeting multiple cars on streets in residential neighborhoods in the city.

Synobia Veney, 26, said it was the third time in about three months that her tires had been slashed on the 700 block of Cornwall Street.

In the previous incidents, all four tires of her 1998 Chevrolet Malibu had been flattened, but this morning only two tires were damaged, she said.

Still, she had to call out from her housekeeping job, Veney said.

"Something has to be done," said Veney, who discovered the vandalism at 5 a.m. as she prepared to go to work. "This can't keep happening."

Police are investigating.
