A man who climbed an Oklahoma TV transmission tower spent a fifth day up there Monday while the spectacle at ground level expanded, a public response that a mental health expert decried as callous.

The 25-year-old man climbed onto the Clear Channel communications tower Thursday and has refused requests to come down, though he has had regular interaction with police.

“He’s talking to us about coming down, but he’s not yet ready,” police Capt. Ryan Perkins said Monday. “He’s just scared.”

Tulsa police said the stalemate — approaching 100 hours Monday afternoon — was the longest in city history.

On the ground, a local television station offered streaming video on the Internet, a number of Twitter hashtags popped up and a restaurant offered a Tower Guy five-topping pizza to mark the man’s fifth day aloft. The climber lost one of his shoes during the weekend, and someone who claimed to have retrieved it was selling the shoe online.

Mike Brose, executive director of the Mental Health Association in Tulsa, equated the host of negative online comments to a drive-by shooting: “I don’t have to take any responsibility; I can basically say what I want.”

Tulsa police identified the climber only as “William,” and video from the tower showed him on a metal lattice about 100 feet up. He wore shorts and a pair of bright red socks in temperatures that climbed well into the 90s since Thursday. At times, the man shouted to the dozens of officers and gawkers below. There appeared to be ample metal on the lattice for him to recline and take a nap.

The online TV feed went dark Monday, which KOTV news director Ron Harig said was so station resources could be used on other stories. He said the station planned to return to the tower to continue covering the standoff.

Perkins said officers were concerned for the man’s well-being because the last time he took water was early Friday. He has repeatedly been offered food and water, but has rebuffed them, Perkins said.
