West Midlands Police have apologised after a police dog attacked a boy in Oldbury.
The 10-year-old suffered serious injuries and is still in hospital, four days later.
The German Shepherd, Belgian Malinois cross was helping officers, after reports of four men stealing copper in the Western Road area of the town.
“This poor young boy has gone through an absolutely horrendous ordeal and my thoughts are with him and his family as he recovers from his injuries.
“We apologise unreservedly for what has happened and have launched an investigation to fully understand exactly how an innocent young lad came to be bitten by a police dog in the safety of his own back garden.
“Police dogs and their handlers receive intensive training and play crucial roles in the arrest of suspects day in day out, but on the very rare occasions where things go wrong, it’s vital we understand why and learn the lessons to ensure it doesn’t happen again."
