The body of one of two University of South Florida graduate students who mysteriously disappeared this week was found on a bridge in Tampa Friday — and his roommate was taken into custody, authorities said.

The remains of Zamil Limon, 27, were found on the Howard Frankland Bridge Friday as the search continued for his girlfriend, Nahida Bristy, 27, law enforcement officials said at a press conference Friday.

Limon’s roommate, Hisham Saleh Abugharbeih, was hit with charges linked to Limon’s death, including failure to report a death and unlawfully moving a body, according to Hillsborough County Sheriff Chad Chronister.

Limon and Bristy, a couple from Bangladesh, were last seen in the area on April 16.

Abugharbeih was arrested after barricading himself inside a Tampa home Friday, officials said.

SWAT teams armed with assault rifles descended on Limon’s Lake Forest neighborhood —  just over a mile from USF’s Tampa campus — around 10 a.m. Friday, WTSP reported.

The raid was tied to the alarming disappearance of the couple soon after officials declared they were deemed “endangered,” without elaborating.

The situation was “resolved” about two hours later, the sheriff’s office said, with Abugharbeih taken into custody.

He was also hit with preliminary charges of domestic violence, battery, and  false imprisonment, and tampering with evidence,  according to Chronister.

Limon, a doctoral student pursuing a degree in geography, environmental science and policy, was last seen at 9 a.m. at his Tampa student apartment complex, police said.

Bristy, who was studying chemical engineering, vanished about an hour later. She was last seen at the Natural and Environmental Sciences Building on the university’s campus, according to cops.

They were reported missing by a friend who said they were unable to get in touch with the pair. Both of their phones had been turned off, investigators said.

The students had recently discussed getting married, Fox13 reported.
