Delta Police say they're conducting an operational review in relation to an attack by two pit bulls late last night.

One of the pitbulls is dead after being shot by one of the officers.

Police say shortly before 11:00 last night, two officers and a police dog were attacked by the pitbulls while they were doing routine patrols in the area of the 700 block of Chester Road.

One of the dogs fled after being hit with a baton, but the other pit bull apparently bit the hand of one of the officers and attacked the police dog.

Police say one of the officers shot the dog after several attempts to fend it off.

The scene was secured and later released.

The dogs' owner and another person arrived while the investigation was going on.

Police say the two tried to obstruct the investigation and were arrested.

They've been released and charges are being considered.

One of the officers was treated at hospital and is home recovering from a bite wound and possible broken bones to his hand.

He needed numerous stitches.

Police say the other officer is reported to have several minor injuries to both hands.

The police dog suffered puncture wounds to the head, ear and eye area.
