According to the Daily Star, the Love Plane, with the words "I am back" written on it, reappeared at its old site in Liverpool after a "hooded figure" was spotted by witnesses nearby.
However, it hasn't been confirmed whether it is an official Banksy work, as the anonymous artist hasn't yet addressed it on social media.
The news comes after Banksy created a new work of art in the Welsh city of Port Talbot, which depicts a little boy playing in dangerous pollution coming from an industrial building.
