Two state troopers involved in the beating of a man who dropped to his hands and knees after leading police on a 50-mile car chase were arrested Tuesday.

Joseph Flynn, 32, of the Massachusetts State Police and Andrew Monaco, 31, of the New Hampshire State Police, have been charged with simple assault due to their use of force.

In a shocking video captured by a TV news helicopter, Richard Simone Jr, appeared to surrender before the vicious attack left him with post-concussive syndrome according to medical reports.

Both Monaco and Flynn punched Simone repeatedly while he was prone on the ground. Monaco also kneed Simone multiple times.

Authorities say Simone, 50, refused to stop for police in Holden, Massachusetts, on May 11, leading them on an hour-long chase with speeds up to 100 mph that ended in Nashua, New Hampshire.

The video shows Simone stepping out of his pickup truck before kneeling and placing his hands on the ground.

The officers are seen approaching him cautiously, until Monaco begins punching Simone on the left side of his head, according to complaints filed against the troopers.

Both Monaco and Flynn punched Simone repeatedly while he was prone on the ground. Monaco also kneed Simone multiple times.

New Hampshire Governor Maggie Hassan said the footage raised 'serious concerns' about use of force.

'We must treat this incident with the utmost seriousness without disparaging all of the hard-working police officers who put their lives on the line every day to keep us safe,' she said.

Flynn has been charged with two counts of simple assault while Monaco was charged with three. They were both suspended.

The charge is a misdemeanor and carries up to a year in jail, but New Hampshire law stipulates more serious penalties to on-duty law enforcement officers.

Each charge is subject to an enhanced penalty of up to five years, the attorney general said.

Simone (pictured being taken into custody) said he was repeatedly told to 'stop resisting' although his arms were behind his back, according to the complaints. The incident was captured by a TV news helicopter

Monaco was released Tuesday on $3,000 personal recognizance bond, and Flynn was released on $2,000 bond.

They are scheduled to be arraigned September 13 in Nashua.

Simone later told investigators he was repeatedly told to 'stop resisting' although his arms were behind his back while the attack continued, according to the complaints.

Simone told investigators he received three stitches in his ear while medical records indicate he was diagnosed with possible post-concussive syndrome following the beating.

Post-concussive syndrome is caused by a head injury, where symptoms like headaches, dizziness, sleep problems, depression, anxiety and cognitive issues can last for weeks or months.
