A serving Metropolitan Police detective was caught by a colleague allegedly committing an indecent act in a public park, a court has heard.

Detective Constable Dariusz Alexander, 48, who is attached to the Met Operations Command, denied a charge of committing an act of outraging public decency when he appeared at Thames Magistrates’ Court in east London on Thursday.

The charge relates to an incident while he was off-duty on Hampstead Heath on March 18.

The court heard the alleged incident was spotted by an officer who was in the area on a different police matter.

Varinder Hayre, prosecuting, told the court that Mr Alexander was seen by two police officers on the heath on March 18.

She said: ‘They were trying to retrieve some CCTV for a different allegation in Hampstead Heath park.

‘One said he had seen a couple walking past the area, along with some others passing by. It was a Saturday, so children were off school.’

‘There is high culpability and abuse of position as he was a serving police officer,’ the Telegraph reported.
