TACOMA, Wash. -- Troopers are investigating several reports of cars apparently being struck by rocks as they drove along I-5 in the South Sound.

William Bamba says he was in the far left lane on his way to work late Wednesday night and as he passed under 84th, he heard the sound of a heavy object his his car. At the same time small pieces of glass flew into his face.

He was able to pull over and called police. He wasn't seriously injured.

Bamba says whoever is responsible is not thinking about the consequences.

"It's stupid," Bamba said. "It's costing people money out of their pockets and it could have killed somebody."

Bamba said the trooper told him there were reports of six other rock-throwing incidents -- three in the area of 84th in Tacoma and three more in Lakewood.

Troopers are investigating these incidents, but they're not saying yet whether somebody is indeed throwing rocks.
