A man pulled out a knife as he returned from the bathroom on a Greyhound bus late Thursday and stabbed a woman, yelling that he had AIDS as he exited the Washington-bound vehicle, police said.
The trip had departed from Atlantic City, N.J. and was passing through Baltimore around 9:30 p.m. The woman was seated at the back of the bus with a male friend when another passenger stabbed her in the neck, stomach and hand, according to a Baltimore City Police report.
The woman's friend then began to punch the assailant, who soon fled.
Alexandra Pedrini, a spokeswoman for Greyhound, said the driver of the bus had pulled over to a safe location and tried to help ward off the attacker.
The assailant attempted to get back on the bus, saying he had left behind his coat, police said, but was locked out. He then ran off toward a wooded area near the 1700 block of Russell Street.
The victim was later taken to a nearby hospital where she is listed in serious condition, police said.
Officers canvassing the area were unable to find the attacker.
He is described as a black man in his mid-30s or early 40s who stands about 5 foot 4 inches tall and weighs approximately 140 pounds. He also has scraggly black hair, a black goatee and was wearing a gray hoodie with blue jeans, police said.
Greyhound is working with police on the investigation, Pedrini said.
