A police officer in Wirral has been docked pay for his part in homosexual activity in public toilets.
Merseyside Police said the matter was investigated properly
The officer, who has not been named, was fined 13 days' pay following an investigation into "cottaging" at toilets on Harrison Drive, Wallasey.
Six people have been charged under the Sexual Offences Act - two have pleaded guilty, four are awaiting trial.
Another 32 people, including the officer, were issued with cautions over the incidents.
A spokeswoman for Merseyside Police said: "One of the people cautioned is a serving Merseyside Police officer and he has also been fined 13 days' pay through the force's disciplinary procedures."
Police said it was standard practice to ask those arrested to identify people they engaged in the offences with.
But the investigation has drawn criticism from the gay community which claimed "policy and procedure" was not followed.
Mike Homfray, chairman of the Gay and Lesbian Police Liaison Group, an independent group funded by Merseyside Police, said: "There is a lot of unhappiness and I feel it did a lot of harm.
"Usually there are warnings put up by police for operations. This was not done. We have been following this quite closely."
An internal investigation is now under way into how the case was handled.
