Tiger Woods' half brother, Earl Dennison Woods Jr., was arrested Thursday after police said he called in a bomb threat to an Arizona Department of Economic Security office in Phoenix. Woods, 58, worked at the office and admitted to supervisors that he called in the threat as a joke, authorities said. Phoenix police responded at about 8:30 a.m. to the DES building at 1824 E. McKinley St. after a caller â€” later identified as Woods â€” said that he had a bomb and was going to blow up the building, said Sgt. Trent Crump, a Phoenix Police spokesman. The building was evacuated and searched, but no device was found. During the search, Woods admitted to management that he called in the threat and he had done so as a joke, Crump said, adding that Woods repeated his admissions to authorities during an interview. Woods was booked into a Maricopa County jail on suspicion of use of an electronic communication device to terrify, intimidate, threaten or harass, which is a misdemeanor.
