Vernon police have arrested a South Windsor man accused of biting a caretaker's nose off because she made a wrong turn on the way to a medical appointment.

Aaron Olmsted, 33, of South Windsor, attacked a woman on Regan Road in Vernon on Monday morning and bit her nose off, police said.

Police said Olmsted knows the woman, who was working for a social service agency and he bit her because she made a wrong turn while taking him to a medical appointment.

The woman called 911 at 9:15 a.m. from a parking lot and told dispatchers the man bit off much of her nose.

Olmsted had run from the scene and police identified him as the suspect.

Vernon EMTs, police officers and a paramedic treated the woman, who was transported to Hartford Hospital.

Police also started searching for Olmsted and found him just before 10 a.m. on Avery Street in South Windsor.

He was arrested, brought to Vernon Police headquarters and charged with assault in the first degree and reckless endangerment in the first degree.

Olmsted is being held in lieu of a $500,000 surety bond and is scheduled to appear at Rockville Superior Court this afternoon for arraignment.
