COLCHESTER Zoo's female Orangutan Djambe died of a heart attack, it has emerged.

The zoo has received the initial post mortem results following the death of the popular primate on October 25.

The results indicated that she suffered a heart attack following the rupture of a large ovarian cyst.

A spokeswoman for the zoo said: “Djambe and her companion, Rajang were moved to the new Orangutan Forest enclosure however, during a medical examination at the time of the move an irregular shaped mass, now known to be an ovarian cyst, was found on the right side of Djambe's abdomen.

“She was assessed by the zoo's veterinary team on the 24th October and a second anaesthesia to examine the mass in her abdomen was planned.

“It is now clear from the post mortem it is highly unlikely that this surgery could have been successful. A plaque at the new enclosure is planned to remember Colchester Zoo's very special female Orangutan.”
