The Daily News reported this morning that a militant animal rights group says it is being investigated by the LAPD's anti-terrorism unit. The Animal Defense League drew attention by posting the home address and phone number of Mayor Jim Hahn and the head of the city's animal services department on its web site and urging they be visited. The group also circulated fliers with the information. "The LAPD is aware of this and closely monitoring the situation," deputy mayor Matt Middlebrook told the paper.
