Bodio Hutchinson, 34, is charged with stabbing two park rangers on Boston Common on Tuesday.

BOSTON — The homeless man charged with stabbing two park rangers on Boston Common was held at his arraignment Wednesday on $1 million bail.

Bodio Hutchinson, 34, was arraigned in Boston Municipal Court on charges of assault and battery on a public employee, assault and battery with a dangerous weapon, and armed assault with intent to murder.

His lawyer said he suffers from paranoid schizophrenia and does not remember Tuesday’s attack.

Meanwhile, the more seriously injured of the rangers is improving.

The 46-year-old veteran, who was in critical condition when he was brought to Massachusetts General Hospital for surgery on Tuesday with stab wounds to the abdomen, is expected to survive, Boston Police Sgt. Michael McCarthy said.

His 23-year-old colleague with less serious injuries was treated at Tufts Medical Center. He is expected to be released Wednesday, said Ryan Woods, a spokesman for the city parks department.

Their names have not been made public.

The rangers, who do not carry guns, were attacked after they approached the man about 4:30 p.m. as he sat on the Civil War Soldiers and Sailors Monument in the park, Boston Police Commissioner William Evans said.

“He lunged at both officers and stabbed them multiple times,” Evans said.

The commissioner said witnesses followed the man and provided cellphone video to police.

A knife was also recovered from a nearby pond.
