A Nicaraguan man who was in U.S. Customs and Border Protection custody died early Friday morning, the agency reported.

The 52-year-old man was among 36 people from Central America who surrendered to Border Patrol agents west of Sasabe, Arizona, according to a CBP statement. Immigration officials were processing the group at a facility in Tuscon.

CBP said the man fell into “medical distress” and was rushed to the hospital. Efforts by emergency responders and CBP agents to revive him were unsuccessful, the statement said.

The agency did not provide the man’s name.

“The men and women of U.S. Customs and Border Protection are saddened to report that a 52-year-old man from Nicaragua was pronounced deceased early this morning after he was rushed to the hospital,” the agency said. “Our condolences are with his family.”
