A father was left “sad and humiliated” after being questioned by police for taking pictures of his own son in a park.

A caller dialled 999 telling police a “suspicious” man was taking photographs a child in a Portslade playground.

The dad was then forced to show his pictures to a policeman to prove he was playing innocently with his five-year-old son.

The 46-year-old, who does not want to be named, said he was baffled that whoever called the police could tell he was with his child.

He said: “Surely someone watching that closely to see that I had a camera could see I was with my son.

“I just thought this is crazy and really sad.”

The pair had gone to the playground on Saturday morning when police were called at about 11am.

Yesterday Sussex Police confirmed that no offence had taken place.

The father said: “I felt completely isolated and humiliated. I will go back to that park. People will think that’s the guy who police came and spoke to.

“It’s just sad.”

A Sussex Police spokesman said: “This incident was reported to police as a suspicious man taking photos of a minor. We have a duty to investigate. An officer spoke to the man and checked his camera and was satisfied it was his son and no offence had taken place.”
