Prominent Baltimore civil rights activist Joseph Kent was arrested Tuesday night on live television while protesting the death of Freddie Gray 40 minutes after the city's nightly curfew.

During a live CNN broadcast, Kent was seen wearing a mask while walking in front of a line of police in riot gear with his hands up around 10:40 p.m. That's when a National Guard truck suddenly drove near him and several officers rushed out and arrested him, whisking the 21-year-old activist away in handcuffs.

Authorities later identified the arrested man as Joseph Kent and announced he is being held on a charge of curfew violation, according to the Maryland Department of Public Safety and Correctional Services.

Following his arrest, a local lawyer named Steve Patrick Beatty tweeted that he is representing Kent and that he is doing well.

"I spoke with him for 20 minutes eye to eye," Beatty wrote. "He is healthy and positive."

Beatty also told CNN that Kent was being processed at the Baltimore Central Booking and Intake, reports USA Today. He has yet to appeared before a court commissioner to have his bail set.

Kent, a student at Morgan State University, gained attention after the 2014 shooting of Michael Brown in Ferguson, Missouri, where, according to the Baltimore City Paper, he helped to keep protests peaceful and organized.

On Tuesday, Kent was participating in protests calling for justice for Gray, a 25-year-old black man who died of an unexplained spinal injury on April 19, exactly seven days after he was apprehended by Baltimore police. According to officials, Gray made eye contact with an officer and then fled the scene on the morning of Sunday, April 12. He was then chased by the officers, some of whom were patrolling the neighborhood on bike. Once they caught up to him, he was taken into custody for carrying a switchblade knife.
