Police will be reviewing CCTV footage as they investigate the break-in at a monkey enclosure in Wellington Zoo.
The zoo reported yesterday that intruders had tried to snatch a squirrel monkey overnight.
Some of the monkeys had been harmed during the attempt with one sustaining a haematoma on its elbow.
Today, a Wellington Zoo spokesperson said the group of squirrel monkeys were settling well but that the team would be "keeping a very close eye on them".
The injuries were minor, he said.
