A man who scaled an Oklahoma TV tower last week resisted attempts to coax him down Tuesday, as the stalemate lasted into a sixth day. Rescue crews continued to offer the 25-year-old man food and water, conditional on him agreeing to come down from his perch about 100 feet up the Clear Channel communications tower, where he has been since Thursday.

A person in a fire department truck lift at times touched the man's hand Tuesday afternoon, seeming to try to persuade him into the bucket, but was rebuffed.

The last time the man took water was early Friday, and officers say they are concerned.

"We're thinking most people would take us up on that offer," said Tulsa officer Leland Ashley. "But, for whatever reason, he's not coming down."

Dozens of onlookers have flocked to the site, and mental health experts have urged caution and compassion from members of the public, who have taken to the Internet to weigh in on the situation.

Ashley said there were no plans to try to force the man down from the tower and said it would be logistically impossible to place a net under the tower in case he fell because the structure is so massive.

"We've had people ask that question and there really isn't a way to put up any type of netting in case he falls," Ashley said. "It truly is a waiting game."

The man was wearing only a pair of shorts as temperatures reached into the upper 90s Tuesday afternoon. There was room on the metal lattice for him to take naps and he continued to occasionally shout at people and officers below.

A Clear Channel spokeswoman said the company's staff in Tulsa found the man in an unauthorized area Thursday morning, and that's when he ran from security guards and scaled the tower.
