A confidential police document about a vulnerable toddler has been found in a street in Cornwall.
The police log, found in a street in Bodmin, was handed to a local newspaper which returned it to Devon and Cornwall Police.
The force said it took data protection "very seriously".
It comes two weeks after a floppy disk with confidential police staff details on it were found dumped at a recycling centre in Exeter.
It is understood the police log, found by a member of the public in Bodmin, discloses police concerns for the child.
Asst Ch Con Bob Pennington said it was unfortunate the document was mislaid and the incident was a lesson for the police.
He said it was rare for officers to print off data but sometimes they needed to when there was a lot of information and they had to respond quickly.
"We understand that the public's concern about issues such as this may have been heightened by other recent stories about data loss within the public sector," he said.
"I would like to take this opportunity to reassure the public we are confident that our existing technology is safe."
An investigation into the incident is under way.
Two weeks ago Devon and Cornwall Police had to apologise to staff after a floppy disk including names, addresses, telephone numbers and ranks of police employees was found dumped at a recycling centre in Exeter.
