Concerns have been raised over a video which appears to show a child being forcefully restrained by police in Banbridge.
Sinn Féin MLA John O’Dowd described the alleged incident as “disturbing”.
“Video footage appearing to show a child being forcefully restrained by PSNI officers in Bainbridge is shocking,” said Mr O’Dowd.
“I understand the Police Ombudsman’s office is investigating the incident which appears to show a child being grabbed by an officer and then falling to the ground.”
He added: “It is believed the child sustained injuries during the incident.
“It’s important the Police Ombudsman can ascertain exactly what happened and I will be contacting the PSNI to raise our serious concerns.
“Anyone who has any information about this incident should bring it forward to the Ombudsman’s Office.”
The video in question has been circulated on social media and is believed to have involved a 12-year-old boy.
