Authorities say an anonymous caller threatened to detonate a bomb inside a mosque in Tennessee on the 10th anniversary of the Sept. 11 terror attacks.

According to a police report, an unidentified person made the threat Monday in a voicemail left at the Islamic Center of Murfreesboro. The report says the message included extreme profanities and derogatory remarks toward Muslims.

Murfreesboro Police spokesman Kyle Evans told The Associated Press on Wednesday that security at the mosque has been increased and that marked and unmarked vehicles are patrolling the area. Evans says federal authorities are helping in the investigation.

The mosque has been the target of vandals who defaced signs at the site where it plans to build a bigger site of worship. Last year, arsonists also torched construction equipment there.
