WEST VALLEY CITY, Utah - Authorities have just released body camera video from a police chase that ended with an officer falling from a roof in West Valley City.

Authorities said the chase started early Tuesday morning back on Nov. 16 when officers were called to a gas station near 4000 W. and 4100 S. about a "suspicious man" who wouldn't leave.

Officers tried to talk to the man but he ran off.

Police saw the suspect, 32-year-old Sergio Ramirez, run into an area under construction and heard the loud noise of shattering glass.

They contained the area and found a business with multiple broken windows and doors at 3940 W. 4100 S.

As officers were getting ready to search the business, other officers saw the suspect on the roof of a strip mall at 3974 W. 4100 S. nearby.

Authorities set up a perimeter around the strip mall and called for a ladder to get onto the roof.

Once officers got onto the roof, Ramirez said he had a grenade and would not cooperate with authorities.

Officers said Ramirez tried to get into the building by tearing out vents and grates which he also threw at officers.

At one point Ramirez charged officers, causing one to lose his balance and fall about 10 feet from the roof onto the concrete below.

West Valley officers said they tried using pepper spray and a Taser to arrest Ramirez but neither seemed to affect him.

Eventually officers were able to restrain Ramirez and take him into custody.

They did not find the grenade or any other weapons on him.

The officer was checked at the hospital for bumps and bruises as a precaution and is doing well.

Ramirez was checked at the hospital and booked into the Salt Lake County Jail on the following charges:

Threats of terrorism

Criminal Mischief

Assault on a Police Officer (3 counts)

Fleeing on foot

Interference with arrest

Disorderly Conduct
