David Sweat, one of two killers who eluded capture for three weeks after escaping a maximum security prison in New York last month, was released from a hospital Sunday and returned to prison, authorities said.

Sweat, 35, was released from Albany Medical Center and sent to the Five Points Correctional Facility in Romulus, the state Corrections Department said in a statement. The department declined to reveal details about Sweat’s transportation from the hospital to Five Points.

Sweat will remain in the prison infirmary for 24 hours for medical evaluation, the statement said. Following his discharge from the infirmary, Sweat will be housed in the Five Points Special Housing Unit in a single cell within the facility’s 150-bed, 23-hour confinement unit. Each cell is equipped with a bed, a writing platform, a toilet and sink, and a facility-controlled shower which the department said will limit movement.

Sweat, who will be placed on active suicide watch, fled the Clinton Correctional Facility in Dannemora, N.Y., on June 6. He and escapee Richard Matt eluded capture in the deep forests of Northern New York State for three weeks.

Matt was fatally shot by U.S. Border Patrol officers nine days ago. Sweat was captured by New York state troopers two days later.

Five Points Correctional Facility currently houses 1,294 inmates and has 669 employees, including 511 security staff.
