The Sikh Federation has called for an independent investigation into the "totally unnecessary" prosecution of two brothers who were arrested during a protest at a temple.
A trial at Birmingham Crown Court, which ended on Tuesday, heard that 55 protesters were detained after armed police were deployed to a Sikh temple in Leamington Spa on September 11 2016.
The proceedings ended in the acquittal of Gursharan and Kulvinder Singh, both from Coventry, who were accused of pulling an official's tie and taking down laminated signs inside the gurdwara.
Commenting on the case, Bhai Amrik Singh, chair of the UK's Sikh Federation, said: "We welcome the unanimous decision of jurors to acquit the two brothers and feel vindicated as we have said all along these prosecutions were totally unnecessary.
"This was a lawful, peaceful protest where Warwickshire Police and the Crown Prosecution Service appear to have been given incorrect and false information by members of the Leamington Gurdwara management committee.
"There should be an independent investigation as this incident at that time brought the law-abiding Sikh community into serious disrepute with a massive over-reaction with armed police being deployed on the anniversary of 9/11."
Mr Singh said headlines at the time of the incident were fuelled by an "irresponsible" press statement released by police, which said a significant number of bladed weapons were seized at the scene.
A further statement issued later the same day said the blades seized had been ceremonial and that an inquiry was taking place into the initial report that other weapons were involved.
Kulvinder Singh's lawyer, Talbir Singh, told the trial that lawful protest had been part of the fabric of British society for many, many years, and that the case was "the largest hammer you will ever see to crack the smallest nut".
