Someone has thrown a baby's car seat through the rear window of octuplet mother Nadya Suleman's minivan.

Police in La Habra, Calif., say the octuplets' nannies saw the seat lodged in the shattered window of the family's gray 2005 Toyota Sienna when they arrived to work Wednesday morning at Suleman's home.

Lt. Fred Wiste says a night nanny heard a noise, looked out a window and saw a white cargo van speeding away around 3 a.m, but did not call police or go outside to investigate.

Officers have no suspects.

Suleman, an unemployed single mother of 14 children, has endured much public scorn in the weeks since giving birth to octuplets on Jan. 26. Her former publicists have received death threats.
