WASHINGTON (AP) -- A Muslim advocacy organization is asking for an investigation into what it says was a bomb threat against a mosque in North Carolina. 

• An advocacy group wants an investigation into a bomb threat against an North Carolina mosque.
• The Muhammad Mosque 36 is located in Charlotte.
• Police say the bomb threat was called in last Sunday. 

The Council on American-Islamic Relations said in a news release it would like the alleged incident investigated as a hate crime. 

Police said someone called in a bomb threat to Muhammad Mosque 36 in Charlotte last Sunday.

Communications director Ibrahim Hooper said at a time of attacks and threats targeting houses of worship, members of minority groups and national political figures, it's imperative that the bomb threat be investigated as a hate crime and the perpetrator brought to justice.

The Washington-based civil rights organization is urging mosques and other houses of worship and faith-based and advocacy organizations to take extra security precautions.
