Authorities would not comment Thursday on whether a group of armed bounty hunters who mistakenly swarmed the Phoenix police chief's home were the victims of a prank.

Phoenix police spokesman Trent Crump says it will take some time to investigate the social media tip that led 11 people to believe a fugitive was hiding in Chief Joe Yahner's house.

Officers arrested 43-year-old Brent Farley, the owner of a local bond-recovery company, after the Tuesday night incident.

He is facing one count each of disorderly conduct and criminal trespassing.

Joe Burns, the former president of the Arizona Bail Bondsmen Association, says any tips obtained from social media should be verified.

He also says the incident underscores the need for Arizona to require training for bond agents and bounty hunters.
