Police have denied claims that the organiser of a march in Middlesborough on Sunday had been arrested on terrorism charges.
They said a 29-year-old man was arrested on Friday over firearms offences.
English Defence League founder Stephen Yaxley-Lennon, better known as Tommy Robinson, had posted on Friday: “Lad who organised Middlesbrough march been locked up on terroism charges.”
Cleveland Police said in a statement: “We are aware of misinformation being shared on social media relating to a planned event in Middlesbrough tomorrow.
“Cleveland Police has not arrested anyone in connection with terrorism offences.
“A 29-year-old Middlesbrough man was arrested yesterday on suspicion of possessing a firearm with intent to cause fear of violence.
“He remains in police custody being questioned and inquiries continue.”
