PHOENIX -- The half-brother of professional golfer Tiger Woods was arrested Thursday, after allegedly making a false bomb threat at the government building where he worked.
Earl Dennison Woods Jr., 58, reportedly called in the threat at the Department of Economic Security building in Phoenix on Thursday morning.
Employees alerted building security, who then called police.
More than 100 people were evacuated from the building before Woods came forward, police said.
Woods reportedly told police the phone call was meant as a joke, and he did not expect his co-workers to take it seriously.
"So in this particular case, by the individual coming forward, it enabled this to end at least quicker this morning," said Sgt. Trent Crump with the Phoenix Police Dept. "He cooperated with our officers, was very cooperative, was apologetic as to what he had done."
Police said he also surrendered the cellphone he apparently used to make the call.
Woods' mother and neighbors said the prank seemed out of character for Woods.
"Something really must have drastically happened," Woods' mother Barbara Gray, who lives in California, told 3TV in a telephone interview.
Neighbors described Woods as a quiet, friendly and normal guy.
"He just welcomed us to the community," neighbor Haley Dawson said. "He didn't seem any different from anyone else here."
Woods' and his younger half-brother have been described as "estranged" in the media in recent years.
He was booked into the 4th Avenue Jail on charges of attempting to terrify, intimidate, threaten or harass others.
The Department of Economic Security has not yet returned a request for comment. It is not clear whether Woods is still employed with the department.
