TORONTO - A 57-year-old amputee says he was told to "hop" after his prosthetic leg was ripped off by a police officer during a G20 protest.

John Pruyn of Thorold, Ont., was protesting near the Ontario legislature on June 26 when police in riot gear tried to clear the area.

The above-the-knee amputee says he was "kicked and punched" by officers and detained for more than a day, while sitting in a wheelchair with his hands bound.

When he asked for his leg, Pruyn says he was told it was a weapon.

Around 900 people were arrested over the G20 weekend after vandals ran wild through the streets of Toronto.

More than 700 were released without charge.

Police say they will not comment on individual allegations, but an independent review of their actions was requested by the Toronto Police Services Board on Tuesday.
