Investigations have been launched into the care of a man arrested after a three-year-old boy was seriously injured in a crocodile enclosure.

The boy was attacked by at least one of the animals at Johnsons of Old Hurst near Huntingdon, Cambridgeshire, on 18 June. Police arrested and bailed a 30-year-old man from Norfolk on suspicion of attempted murder.

Norfolk County Council – which did not itself provide any care for the man – has launched an inquiry under the Care Act 2014.

A spokesperson for the Care Quality Commission (CQC) said it was “conducting an assessment of the related registered provider”.

Cambridgeshire Police said it was called to the zoo at about 13:30 BST on the Thursday of the attack.

The boy, from Cambridgeshire, was visiting the zoo with his family. He remains in Addenbrooke’s Hospital, Cambridge, where he is stable.

His family said he had subsequently undergone surgery five times and faced lengthy rehabilitation.

The arrested man was believed to have learning disabilities and had been on a trip to the zoo with carers. He was not believed to have known the child.

He was released on bail until 18 September, and police said he was “assessed as not being fit for interview”.

A spokesperson for the county council said: “The individual in question is not receiving any care provided, commissioned or paid for by Norfolk County Council.”

A Section 42 inquiry is a statutory safeguarding process under the Care Act 2014 to protect adults with care and support needs from abuse or neglect.

A CQC spokesperson said it had “begun the process of taking regulatory action to address concerns identified as part of this assessment”.

“As part of our assessments, should we find evidence of immediate risk, we will always use our regulatory powers to keep people safe,” they added.

“We continue to liaise with partner agencies as they take forward their safeguarding investigation.”
