Police in Milton Keynes are appealing for witnesses following a robbery in Beanhill.
At around 8.30pm on Sunday (June 28) the victim was in a house on Lammas when she heard a noise in the back garden.
She found her fence panels being held up by two men and a third man in her garden taking a motorbike. She went out and challenged them and tried to put the bike in the house.
Before she could do so, one of the three men grabbed the bike and pulled, causing her to fall to the ground.
A second man started to kick her leg and shouted at the other two men to grab the bike. A third man grabbed hold of the bike and took it from the garden.
The victim started to scream and the three men ran off with the bike. They went into the field next to Capron, started the bike and left in the direction of Netherfield.
The bike that was stolen is a blue Thumpstar off-road motorbike.
