A zoo in Melbourne, Australia was sent into lockdown when an orangutan had escaped from its enclosure. Staff members believe that Malu the Sumatran orangutan had escaped using a blanket to break the top wire of his enclosure then walked along the roof to break out and walk around the zoo, albeit briefly, according to Nine MSN.

Staff members were able to usher the visitors to a secured area and lock down the zoo but they were allowed back in once the orangutan was captured.

"At no stage were visitors or staff in danger," said a spokesperson for the zoo.

The orangutan was eventually cornered and captured by the zoo's staff members, brought to an undercover area then tranquilized at around 4:30 in the afternoon Australian time.

"He has been transferred to his night quarters and will be monitored by vets and keepers," said the spokesperson, according to the Daily Mail.

The spokesperson added that the orangutan had been trained to hold out his arm to take shots, which was put to good use when staff members tranquilized him.

Malu will remain in the undercover area and will not be back on display until the roof of his enclosure is repaired, according to Perth Now Sunday Times.
