The Boston Police Department confirmed that the suspect was apprehended at 8:45 p.m. ET after a harrowing manhunt that shut down the city of Boston and the surrounding areas.
Shortly before his capture, Tsarnaev exchanged gunfire with authorities in Watertown, Mass., and took shelter in a boat stored in a resident's yard.
Boston Police said in a press conference at 9:45 p.m. ET that Tsarnaev was in serious condition at a local hospital. He is the only known surviving suspect in the bombings.
Dzhokhar's brother, Tamerlan Tsarnaev, was killed in a shootout with police early Friday morning.
A later Friday night Tweet from the Boston P.D. proclaimed: "Captured!!! The hunt is over."
