Canterbury police are appealing for help to find the identity of a four-year-old boy.
The child was found in the Hoon Hay area on Saturday afternoon. Police say he's wearing Ben 10 pyjamas and pushing a plastic lawnmower.
Unfortunately, his caregivers have yet to contact police so far.
"If the caregivers haven't noticed him missing you'd have to hope they themselves are safe. Very scary and distressing indeed," one person commented on Facebook.
If you know who he might be, please call Christchurch police on (03) 363 2500 or email firstname.lastname@example.org.
