Police are trying to identify people who posted “homophobic” leaflets through doors after the Preston Pride festival at the weekend.
Officers say they want to speak to those responsible, although they believe no actual crime has been committed.
“We are aware of a number of leaflets that have been distributed,” said a spokesman for Lancashire Constabulary. “But at this stage we are satisfied that no offences have been committed, although we do recognise that some people may have found the content offensive and upsetting.
“We have completed a number of incident reports and we will continue to monitor the situation and hopefully identify the individuals responsible for delivering them with a view to discussing the impact the leaflets have had.”
The leaflets, which say homosexual is immoral and not natural, were handed to police by organisers of the festival.
Chairman Steve Griffin, who suspected they were the work of religious extremists, said: “Obviously it’s upsetting. I understand there are laws we need to follow, but what would happen if we went round and stood outside their church and said that religion was wrong?
“It’s not the first time something like this has happened. They think the gay lifestyle is wrong.
“But what is interesting is they always seem to quote the Old Testament. If they quoted the New Testament, they’d see that it says ‘love thy neighbour’.”
