A 25-year-old English Defence League member has pleaded guilty to daubing hate graffiti on land being considered as a site for a mosque.
Christopher Payne of Hucknall admitted spraying the graffiti but denied putting a pig's head on the site in West Bridgford, Nottinghamshire.
He appeared at Nottingham Magistrates' Court and will be sentenced on 21 July.
Police went to the property on 23 June where the slogan "No Mosque Here" was found spray painted on the ground.
Payne pleaded guilty to causing racially or religiously aggravated alarm, dissent or distress and causing racially aggravated criminal damage.
Three other men aged 19, 21 and 31, have been arrested and questioned about the incident.
Payne, of Beardsmore Close, Hucknall, who is an events planner for the English Defence League, told the court that he sprayed the slogan but did not put the pig's head on the grassland.
He was granted bail with a curfew but ordered to stay out of West Bridgford and not to go within 200m of a mosque.
He has also been told not to have any public association with the English Defence League.
A member of the public reported finding the graffiti near Collington Way in West Bridgford on Thursday.
