A LaGrange woman is in Dutchess County Jail on Monday after launching a pair of unprovoked attacks with a steak knife Saturday night on three women in the city of Poughkeepsie, police said.

Chantasia Griffin, 20, faces one count of first-degree assault and two counts of second-degree assault, felonies, city of Poughkeepsie police Sgt. Walter Horton said on Monday.

At 8:07 p.m. Saturday, police received a report from two women who said they had left a downtown restaurant and were walking to their car along Main Street, between Market Street and Columbus Drive in the area of the Mid-Hudson Civic Center, when they were confronted by Griffin, who attacked them both before fleeing, Horton said. One victim was cut on the cheek and the other received a small puncture wound on the chest, he said. Neither required hospitalization.

At 8:19 p.m., another woman told police she had been stabbed in the back twice in the area of 135 Mill St. before her assailant fled, Horton said. She suffered a collapsed lung in the attack and was taken to Saint Francis Hospital in the Town of Poughkeepsie, where she remains Monday, Horton said. He did not have details on her condition but said her injuries are not believed to be life-threatening.

Both attacks were completely unprovoked and none of the victims knew Griffin, Horton said. "There was no conversation, no demand for money," he said.

Police checked the area and based on the victims' descriptions, found Griffin near the taxi stand at the Poughkeepsie train station, Horton said. The first two victims identified her as their attacker at the police department headquarters and the third victim identified her based on a booking photo, he said.

The incidents remain under investigation and it is not yet known if alcohol or drugs played a role in the attacks, Horton said.

Griffin's next court date is Tuesday, Horton said. No further information on her arraignment or legal representation was immediately available Monday.
