GRAND RAPIDS, MI -- A man who was charged with resisting police - and later acquitted - is described as acting "out of control" and "growling like an animal" during a confrontation with officers, according to a police report outlining the incident.

The police report of the July 18, 2014, arrest of James King in Grand Rapids is the latest documentation available from an incident that's now at the center of a federal lawsuit alleging unreasonable search and seizure, excessive force and malicious prosecution.

The report was released to MLive and The Grand Rapids Press through a Freedom of Information Act request.

A Kent County Circuit Court jury in February 2015 acquitted King of assaulting/resisting/obstructing an officer causing injury, felonious assault, and assaulting/resisting/obstructing an officer.

King, 23, and police appear to be telling opposite versions of events.

The physical struggle occurred while a plainclothes Grand Rapids Police detective and FBI special agent were working as part of a West Michigan fugitive task force in search of a home invasion suspect seen in the area. They thought King matched their description of the suspect and stopped him while walking in the area of Leonard Street and Tamarack Avenue NW.

King's lawsuit filed earlier this month states he thought he was being mugged when the detective and special agent asked for his identification and held him against an unmarked SUV. He claims the men didn't identify themselves as law enforcement, and he couldn't see what their badges said.

Grand Rapids Police Detective Todd Allen wrote in the police report that he and FBI Special Agent Douglas Brownback showed King their badges and told him they were investigators looking for a suspect wanted on a felony warrant. Allen said he was wearing a second police belt badge and his department-issued handgun. The report says King later told a responding officer that "anyone can buy a badge" and "I thought they were robbing me."

King gave his first name and told them he didn't have identification while also refusing to provide his last name. Allen told King they needed to verify he wasn't the suspect.

Allen took a folding knife that was clipped to King's pants and gave it to Brownback. Allen patted him down for further weapons and felt a wallet in King's pocket then questioned his claims of not having identification. The police report states King became "verbally combative and aggressive."

Allen said he and Brownback believed King was their home invasion suspect trying to avoid being identified.

King said he asked if he was being mugged, at which point Brownback grabbed his arm. King turned and ran before the men tackled him to the ground, according to the lawsuit.

The police report tells a different story, saying King swung his fist toward Brownback's face after the FBI agent grabbed his wrist.

"King then spun towards us squaring up in a combative manner. He began yelling that 'we did not want to do this' and that he had '3 buddies down the street that were going to come help him,'" Allen wrote in the report.

On the ground, King bit Allen's bicep. The lawsuit said he bit the arm that was around his neck "in a panicked attempt to save his own life" after being placed in a chokehold. King claims Allen rapidly hit him in the head and face.

Allen portrayed King as the aggressor, saying King continued to bite down harder "as he was growling and grunting in an aggressive manner." With King's locked bite on his bicep, Allen said King got a hold of a pair of handcuffs and struck him in the head, neck and back.

Police said King was acting irrationally and they thought he may have been experiencing excited delirium.

Uniformed officers arrived after several bystanders called police.

The lawsuit quotes bystanders from videos they recorded, which did not include footage of the fight. One person said the officers were "pounding his head for no reason. They were being brutal."

Witnesses whose accounts were included in the police report said the investigators yelled for King to stop resisting during the struggle. A woman who didn't see the beginning of the struggle said she initially thought it was a case of police brutality, but changed her mind when King continued to fight with the investigators. She said he refused to let go when biting Allen's arm.

A man who was working at a nearby oil change business heard someone call for help and ran to help detain King by holding his legs down.

King suffered swelling to his face, and photos contained in the lawsuit show the whites of his eyes turned almost completely red and black after the altercation.

Allen wrote in the police report that doctors told him he likely suffered a concussion as well as possible nerve damage from the deep bite to his arm. Brownback was treated for cuts and swelling to his hands.

Grand Rapids Police Officer Connie Morris, an officer who responded to the scene, is named as a defendant in the lawsuit along with Allen and Brownback. She's accused of ordering several bystanders to delete video of the incident for the safety of undercover officers, which the lawsuit says violated King's freedom from malicious prosecution and his right to due process.

King is seeking compensatory and punitive money damages, as well as attorney fees.

Police have declined comment and have not yet filed responses to the lawsuit.
