The half-brother of golf star Tiger Woods has been arrested in Phoenix for allegedly making a false bomb threat at the government building where he works. Phoenix police say 58 year old Earl Dennison Woods Junior is accused of calling in the threat at the Department of Economic Security building Thursday morning. Police say they were called after DES employees alerted building security. More than 100 people were evacuated from the building before Woods came forward and told police the phone call was meant as a joke and he did not expect his co-workers to take it seriously. Police say Woods has been booked on suspicion of attempting to terrify, intimidate, threaten or harass others. They say Woods is apologetic and cooperating with the investigation. It is unclear if he has a lawyer.
