MIAMI BEACH, Fla. – A man has been taken into custody after a woman's body was found inside a Miami Beach apartment Wednesday night.

Miami Beach police Officer Ernesto Rodriguez said the SWAT team and hostage negotiators went to 7441 Carlyle Avenue after receiving a 911 call from a woman who was concerned she hadn't seen her friend since mid-October.

"She attempted to knock on the door," Rodriguez said. "The male inside slammed the door on her, which is when she then contacted police."

Upon arrival, police made contact with a barricaded man who was armed with a knife. Police said the man was naked in bed while holding the knife.

After arranging a peaceful surrender, officers took the man into custody without further incident.

Police then searched the apartment, discovering a dead woman inside.

The identity of the body will not be released until authorities have notified next of kin.

"At this point we believe this was a husband and wife situation," Rodriguez said.

An investigation is ongoing.
