Vancouver police are asking the public for help in identifying a woman caught on a surveillance video trying to sell one of four bronze plaques stolen from Queen Elizabeth Park last month.

The plaques went missing on June 19, the same day a large bronze statue of a woman was stolen.

Police said the video shows a woman visiting a metal scrap yard the day after the theft trying to sell one of the missing plaques, Const. Jana McGuinness said Thursday.

The woman is described as being in her late twenties or early thirties, five-foot-three, about 110 pounds, with dark shoulder-length hair with red or purple streaks, and a tattoo on her left shoulder.

Police said the tip came from the scrap dealer who was asked to purchase the plaque, but refused to identify the dealer in the interest of maintaining good connections with the industry.

The missing plaques were set up in the park to identify geographic sites of interest. The missing statue is a life-size figure of a woman that was part of public art piece called Photo Session, which depicts a photographer taking a picture of three people.
