Hawzah News Agency - (Essex - UK) - Essex Police are investigating after the stickers, which they described as anti-Muslim, were placed over various bus stops in Long Road, Canvey.
The stickers were reported to the police on May 29, and now they are seeking the public's help in finding out where they came from.
A spokesman for the police said the force have been carrying out house to house inquiries and are reviewing CCTV footage in the area.
The incident is the second case where anti-muslim posters have been put up in South Essex.
Around May 19, at least a dozen posters, carrying a white supremacist logo, went up on roads in Rayleigh with the message 'Islamists not welcome', and 'stay back or we will kick you back'.
They appeared to contain a picture of a knight on a horse with a lance, chasing two figures holding an AK47, with one dressed in a Burka.
