In Arizona, police have seized four mosques in a raid by an Arizona sheriff’s office and the local sheriff’s department.
The arrests came on Saturday, according to Arizona’s Fox News affiliate, WFAA.
The mosques are located in Tucson and Phoenix, respectively.
Police say they are taking custody of the mosques for possible criminal charges.
The Phoenix mosque, which has been under the control of the Islamic Society of North America (ISNA), was raided in April and the Tucson mosque was raided on March 23.
The mosque has been receiving money from the mosque’s executive committee.
The local sheriff has previously said that the mosque was a threat to national security and would be taken down.
A local news station reported that the FBI has also been involved in the investigation, though it is unclear if it is related to the mosque raids.
The state attorney general’s office did not immediately respond to Al Jazeera’s request for comment.
