Experts have confirmed a new graffiti mural that has appeared in Camden Town is yet another imitation Banksy.

The small stencil on the corner of an office building on Oval Street shows a small girl with a lollipop, wheeling a surface-to-air missile behind her.

Eagle-eyed Twitter users first identified the painting as a Banksy, because it looked similar to the stencilled graffiti that has made the street artist a national celebrity.

His sometimes irreverent stencils have been a point of contention in Camden Town recently as the celebrated graffiti artist appears to be immune to criminal charges by dint of anonymity.

Meanwhile, not so anonymous street artist Tox, who also paints in the area, was sentenced to 27 months in prison for criminal damages last July and this week lost his appeal against the conviction.
