Oregon Attorney General Ellen Rosenblum announced her intention to file a lawsuit against several federal law enforcement agencies for their actions during protests in the city of Portland, where the unrest has not subsided for a month and a half, local TV channel OPB reported on Saturday.

Rosenblum wants to get a temporary ban on police detentions, arguing that they were carried out for no apparent reason. The defendants will be the Department of homeland security, the marshals’ Service, Customs and border protection, and the US Federal security service.

Also, the Prosecutor announced her intention to initiate a criminal investigation into the shooting of a 26-year-old protester in the head by one of the law enforcement officers with a “non-lethal weapon,” who was seriously injured and has been in the hospital for a week. This case is already being investigated at the Federal level with the filing of the Federal Prosecutor for Oregon, Billy Williams.

Mayor Ted Wheeler earlier demanded the withdrawal of Federal forces from Portland.

According to the TV channel, in recent days, Federal law enforcement officers have been patrolling the city in unmarked cars and making detentions without explanation. As of Friday, 13 suspects had been charged by federal authorities in connection with the unrest.

Federal forces arrived in the city on the eve of Independence Day on July 4. Since then, they have provided security for the Federal courthouse and helped local police disperse protests.
