The silhouette of two pelicans, one eating a fish, appeared above Bonners Fish Bar in Walthamstow in the northeast of the capital on Friday morning.

An employee told Sky News they were not aware of the artwork until this morning, with the takeaway posting on Instagram: "So proud to have a @banksy on the side of our shop! Thank you for choosing us, and Walthamstow for showcasing your talent."

The anonymous artist shared a picture of the piece on his Instagram on Friday.

It comes after thousands of people took to the streets in Walthamstow on Wednesday for a counter-protest against far-right groups targeting mosques and spaces used by asylum seekers.

On Thursday, a silhouette of a howling wolf painted on a satellite dish in Peckham, southeast London, was removed by a group in balaclavas just hours after it appeared.

The day before, three monkeys appeared swinging from a train bridge over Brick Lane in the east of the city, not far from Shoreditch High Street.

On Tuesday, a stencil image of two elephants greeting one another from bricked-up windows popped up in Chelsea.

And on Monday an ibex goat was seen painted just above a CCTV camera near Kew Green in the south west of the capital.

Banksy usually leaves months between his artworks, confirming them soon after they appear on social media.

With one posted every day so far this week, there has been much speculation about the meaning behind the animals, but he has not captioned any of the photos shared on Instagram, adding to the mystery.

The Bristol-based anonymous artist made headlines in June when he released a migrant boat installation over the crowd at Glastonbury during performances by Idles and Little Simz.

He was behind another artwork discovered on the side of a block of flats near Finsbury Park, north London, and subsequently vandalised in March.
