Police warned Memphis residents to stay indoors while they searched for the man, while distributing his photo.

The first alert warned of an armed and dangerous man who was responsible for multiple shootings.

“We are getting reports he is recording his actions on Facebook,” police said.

There were no initial reports of anyone killed or wounded.

One brief video posted on Facebook showed a man rambling “this is for real” and using coarse language as he opened the door to a retail store and fired twice at the first person to come into view.

Reuters could not verify the video’s authenticity.

Memphis tranport authorities shut down the city’s bus and tram services, while entrances to a music festival were blocked and guarded by police.

KAIT television reported the suspect had fled across the Tennessee state line into Arkansas in a car.

US media outlets reported a short time ago that US police said they had arrested the man after he crashed a car.
