An infant’s cries rang through the Occupy DC encampment in McPherson Square Wednesday morning, and when a group went to investigate they found only a baby girl alone in a tent, wearing a onesie and mittens.

Soon after, authorities said, a man had been arrested and the girl — who was unharmed — was in the city’s care.

The campers notified authorities and then cared for the girl until help arrived, according to Kelly Canavan, 36, a retired Prince George’s County school teacher who has been living at the camp.

D.C. Fire/EMS workers checked on the girl around 10:30 a.m. She was fine, according to Sgt. David Schlosser, a U.S. Park Police spokesman, and is now with the District’s child protective services department.

About 30 minutes later, Schlosser said, a man returned to the encampment and identified himself as the baby’s father. Police arrested the man, charging him with attempted second-degree cruelty to children.

“Mid 40s, rainy, onesie, alone,” Schlosser said, describing the circumstances that led police to arrest the man.

Schlosser said he did not yet have the name of the man arrested because he was still talking with detectives.

Canavan said the man was not a familiar face in the encampment and had only pitched his tent there this week. The camp has been in the park since Oct. 1.

“None of us knew this person,” she said. “It was a despicable, atrocious thing do. Every one here is revolted by the behavior.”
