'They kept running into the walls and fence': Chaos as two terrified deer rampage through streets of Sydney's inner west

Two deer who were spotted roaming through three Sydney suburbs on Tuesday morning have been captured by police.

The two animals were seen prowling down streets across Leichhardt, Balmain and Annandale in the city's inner-west.

CCTV footage taken in Coleridge Street in Leichhardt showed the two deer walking one behind another in front of a unit block.

One resident said she saw the animals while driving to the gym at 5.30am, while another reported them entering a residential complex about 7.50am. 

New South Wales Police have captured one deer, but as of midday the other is still on the loose.

The local whose surveillance camera captured the deer's movements at 6.30am told Daily Mail Australia her husband checked the footage after he was awoken to the noise outside.

'The roads were fairly quiet so some movement coming up on my left-hand side caught my attention,' one woman who was driving to the gym told Guardian Australia.

'At first, I thought it was a dog running and then I noticed there were two animals running closely together and wondered what sort of dogs are that tall?' 

The reason for the deer's early morning stroll remains unclear.

Another resident wrote in a local community Facebook group she thought she was 'imagining it' when she saw the deer marauding down Mackenzie Street. 

'Managed to coax it out the gate as it was really distressed, kept running into the walls and fence,' one resident who found a deer stuck in her apartment building said. 

Police confirmed one of the deer had been captured but the other was still at large. It's unclear how they made their way to the urban area.

The bizarre scenes come after three baboons were on the loose outside one of Sydney's busiest hospitals for more than an hour in February. 

Animal handlers and police recaptured a male and two female baboons from the car park outside Royal Prince Alfred Hospital at Camperdown in Sydney's inner west after a 90-minute stand off.

The baboons were contained to the car park after escaping through a truck door while being transported to the hospital, where the male baboon was due to have a vasectomy.
