NEWLY RELASED PHOTOS show the Boston Marathon bombing suspect with a bloodied face, climbing out of a boat in a suburban backyard as heavily armed police officers waited for him to drop to the ground.

The images were among those a state police officer provided to Boston Magazine last month. The magazine published some then and more yesterday.

Sgt. Sean Murphy took the photos on that night in April when police cornered Dzhokhar Tsarnaev, 19,  in a dry-docked boat in Watertown, just outside Boston. He wasn’t authorized to release the photos but said he was angry about a Rolling Stone magazine cover he felt glamorised Tsarnaev. Murphy has been relieved of duty because of his actions.

The new photos include more shots of Tsarnaev coming out of the boat, his head bloody, raising his shirt to show he has no weapons and a red laser trained on his head. They also show him dropping to the ground, where officers and medical personnel rushed to treat him. Other photos show tense federal, state and local police officials meeting in a command center and SWAT teams gathering in the streets earlier in the day.

The surgeon who treated Tsarnaev, an ethnic Chechen Muslim, a naturalized US citizen, after his capture said he had been shot through the face and had a fractured skull, among other injuries. Tsarnaev was wounded during a confrontation with police a day after authorities released photos of him and his older brother as suspects in the deadly April 15 marathon bombing.

Tsarnaev has pleaded not guilty to charges in the bombing, which killed three people and injured more than 260 others. His older brother, Tamerlan Tsarnaev, was killed following a gunbattle with police.

Here are the images of the bombing suspect’s capture:
