The body of a Bronx boy who went missing a week ago is believed to have been found in the Hudson River, according to a law enforcement source.

Alfa Barrie, 11, disappeared with a buddy sometime between the afternoon of May 12 and the morning of May 13, authorities said.

“We believe it’s him,” a police source said.

The body was pulled from the Hudson early Saturday after the FDNY was called at 6:49 a.m., the department said.

The body of 13-year-old Garrett Warren, of Harlem, was pulled out of the Harlem River on Thursday, police said.

Authorities recovered Warren’s body near the Manhattan side of the Madison Avenue Bridge that morning.
