HPD SWAT negotiators spend hours trying to talk man down from roof, before deploying taser to end standoff

HOUSTON –HPD SWAT negotiators spent the scorching afternoon Friday trying to talk a man down from the roof of an apartment complex in northeast Houston.

Police were dispatched to the 9000 block of Sterlingshire due to a family disturbance call.

They said the man was involved in some sort of altercation with two women, both of whom he has children with.

The man allegedly threatened them with a knife, and at some point, climbed from the balcony to the roof.

The man could be seen, at times, running from one end of the roof to the next — talking to people on the ground — and other times sitting on the edge while police tried to persuade him to surrender.

The man was shirtless and sweaty under the blazing hot sun, but showed no signs of giving up for hours.

He had his shirt draped around the neck of his thin frame most of the time, when he wasn't wiping off his sweat.  He seemed calm in the beginning, but tensions escalated and began yelling at authorities, appearing to grow more agitated as time went by.

He almost appeared to toy with the officers, constantly going to the ladder that was situated near the roof, but instead of coming down, he'd jiggle it and move away.

While news cameras watched and crowds grew, he began to rant around 4:45 p.m., and authorities said he had already been on the roof for at least a couple of hours.

Exactly at 5 p.m., SWAT officers climbed atop the roof and deployed a taser, knocking the man flat on his back.

They then gathered him up, and brought him down to the ground.

He was alert and appeared to be physically OK -- or well as can be expected -- before they strapped him to a gurney and transported him to the hospital.
