A man grabbed his sister's gun while they argued in their mother's Edina hospital room and threatened to shoot her with the weapon, according to charges filed Thursday.

Larry Sharp, 65, of Independence was charged in Hennepin County District Court with threats of violence, a felony, and two misdemeanor counts of domestic assault in connection with the incident at M Health Fairview Southdale on Tuesday. The hospital briefly went on lockdown as heavily armed law enforcement moved in.

Sharp is jailed in lieu of $30,000 bail ahead of a court appearance Thursday afternoon. His attorney, Eric Nelson, has been contacted for a response to the allegations.

After his arrest, the charges read, Sharp told law enforcement he decided to "disarm [his sister] for safety reasons." He added that he fled from the hospital "'to get ahead of this,'" the charges continued.

Court records in Minnesota show that Sharp has no criminal history.

Law enforcement from several agencies swarmed the hospital on France Avenue just south of Crosstown Hwy. 62 about 3 p.m., according to the charges, related court documents and police accounts. Officers at the scene learned the sister was visiting her mother in an eighth-floor room when the brother arrived.

"An argument ensued [between the siblings] regarding power of attorney for their mother," a court filing read.

During the argument, the sister said, Sharp punched her several times in the head and shoved her into a chair as her mouth was bleeding.

She said he took her gun from her waistband, pointed it at her and threatened to shoot her. Sharp left the room without firing a shot and put her gun on a table outside the room, the charges said.

In all, the sister said, Sharp hit her in the face, head and throat eight to 10 times.

Police later seized the gun. The sister has a state-issued permit to carry a gun in public, the criminal complaint noted.

A witness reported to police that she heard a female yell for help and saw Sharp pointing a gun toward someone in the corner of the room.

The sister told police her brother drives a Ford F150 pickup truck. Police tracked his cellphone's movements showing he was heading home. West Hennepin police went to the man's home and arrested him.
