Dzhokhar Tsarnaev, the Boston Marathon bomber, filed a $250,000 lawsuit against the Federal Correctional Complex Florence over his treatment at the Colorado jail facility where he is serving a life sentence, The Associated Press reported Friday.

Tsarnaev accused jail guards of confiscating his bandana and white baseball cap that he bought at the prison commissary and for limiting him to only three showers a week, the Boston Herald reported.

In his handwritten complaint, Tsarnaev said the confiscation of his personal belonging was "unreasonable and discriminatory" and that it caused him a great deal of "mental anxiety."

Tsarnaev is representing himself in the lawsuit.

Tsarnaev claims that prison guards confiscated his baseball hat and bandana because, by wearing it, "I was 'disrespecting' the FBI and the victims" of the bombing, he wrote in the complaint.

"There's no sign or indication that this abuse will stop in the next six months without the court's intervention," Tsarnaev wrote.

Before authorities identified Tsarnaev on surveillance video, he was referred to as the main suspect seen donning a "white hat" while walking away from the blast, reports said.

The baseball hat was evidence during his death-penalty sentencing, but a court struck down the capital punishment in the summer, according to reports.

A judge said Wednesday the filing was "deficient" because it lacked a certified copy of "prisoner's trust fund statement" and a $402 filing fee.

Three people were killed and more than 260 were injured when two pressure cooker bombs were detonated near the marathon's finish line April 15, 2013.

Tamerlan Tsarnaev, Tsarnaev's older brother, was killed by police three days later.

Officers from the Federal Bureau of Prisons didn't immediately respond to a request for comment, Thursday.
