A crime-fighting parrot has saved his owner after she was pushed to the ground in a park.

Wunsy the African grey was being taken for a walk and fly around when his female owner was grabbed by the shoulders and shoved.

He flapped his wings and squawked, causing the attacker to flee in Hendon, north London.

PC Chris Cutmore said: "This was a random attack on a woman walking out of a park.

"Although the parrot, Wunsy, came to her rescue, we are obviously very keen to trace the suspect and prevent him from attacking anybody else."

Police said the attacker was aged 25 to 35 with short blond hair. He was wearing beige trousers and had a dark black rucksack.
