Several police cars and ambulances rushed to a house in Viking Mews, Thetford, at about 12.25pm on Wednesday after reports of the attack.

A woman, who is in her 20s, and a teenage boy both suffered arm injuries at the property..

Officers took the dog - which one neighbour described as a "Pit Bull type" - to the vets, where it was put down.

Inacio Saloio, who has lived nearby for around 11 years, said: "This is the first time something like this has happened here."

Awa Bailey, a neighbour, said she didn't realise anything had been going on until she opened her door and saw the street "crowded".

"It was a shock," she added.

"It was so scary - it is normally so quiet and happy here."

Another neighbour, who did not wish to be named, also spoke of her shock at the incident.

She said: "There was everything going on all at once.

"It was shocking because this is not something you expect in your area."

The injured woman was taken to the West Suffolk Hospital for treatment and has since been released and the teenage boy was treated at the scene.
