North Charleston police say a burglar alarm led them to a man with more than 100 grams of cocaine in his pockets and an apartment with a sawed-off shotgun and more drugs inside.

The first officer responding to the tripped alarm at 4011 Niagra St. about 3:20 p.m. Monday saw a man exit the front door.

Here is what happened, according to an incident report released Tuesday:

The man attempted to run from the officer but fell. The officer deployed his Taser but it didn't work, allowing the suspect to scale a fence. The officer fired the Taser again, striking the suspect in the back and buttocks. The suspect fell to the ground and kicked off his shorts as the officer ordered him to his stomach.

The officer used the Taser again as the suspect continued to resist. As he was placed in a patrol car, officers found two plastic bags containing a total of 103 grams of cocaine in the pockets of his shorts. They also recovered $48, a cell phone and a digital scale.

Police charged Shane D. Jenkins, 22, who gave police an address of Indian Street in Charleston, with trafficking cocaine.

Officers cleared the house and recovered seven grams of marijuana, two grams of cocaine and a sawed-off shotgun.

The suspect gave police conflicting stories about whether he lived inside the home, according to Spencer Pryor, department spokesman.

He said the case is still under investigation.
