Suspect sought in theft of rock signed by Yoko Ono

Toronto police have released a photo of a woman accused of stealing an expensive rock signed by Yoko Ono.

The rock was part of an interactive display at the Gardiner Museum.

The exhibit was created by John Lennon's widow, who wrote "love yourself "on the rock.

It went missing last month, but police have now released the woman's picture that was caught on a security camera.
