Media regulator Ofcom has rejected police claims that a Channel 4 programme was “distorted”.
The programme, Dispatches, tackled claims of Islamic extremism and featured preachers at various mosques.
West Midlands Police and the Crown Prosecution Service said the programme was heavily edited and distorted what the preachers were saying.
But Ofcom said it found no evidence the broadcast, Undercover Mosque, had misled its audience.
In a statement it said Undercover Mosque, a one-hour documentary shown in January, was a legitimate investigation, uncovering matters of important public interest.
“Ofcom found no evidence the broadcaster had misled the audience or that the programme was likely to encourage or incite criminal activity.
“On the evidence (including untransmitted footage and scripts), Ofcom found the broadcaster had accurately represented the material it had gathered and dealt with the subject matter responsibly and in context.”
