Are dogs being trained to fight in Tibetan Peace Garden?

This week marks the 15th anniversary of the Tibetan Peace Garden at Geraldine Mary Harmsworth Park which was opened by the Dalai Lama in May 1999.

"Unfortunately there is new damage to the bases of trees in the peace garden, which is a recurrent problem in the park," said Jessica Kennedy, chair of the Friends of GMH Park, writing on the group's website.

"It is believed that this is caused by people who are abusing dogs by training them to attack the trees, to increase their aggression levels. This is possibly in preparation for illegal dog fights, including gambling, which have been witnessed in the park.

"If you see the trees being damaged, and you are able to describe the people or dogs involved, please do get in touch."

• The head gardener at GMH Park is leading a walkabout this Friday.

• The peace garden was created by the Tibet Foundation which has recently moved its offices to Westminster Bridge Road.
