We're not yanking your chain with this story: Two people who were allegedly "getting lucky" in a public park ended up getting arrested by 25 cops on bicycles.

Jennifer Harvey, 41, and Richard McBride, 37, were arrested Tuesday afternoon after officers -- 25 of them, all on bikes -- say they saw them having sex on a bench near a baseball field at Naylors Run Park in Upper Darby, Pa.

"There they are, on the first base line. There's a bench, she is bent over the bench and our friend is behind her with his pants down to his ankle, banging away," is how Upper Darby Police Superintendent Michael Chitwood colorfully put it to Philly.com.

The 25 were participating in a "bicycle school" when they saw the couple in alleged action, WPVI-TV reported. The authorities were the only ones in the vicinity when they made the arrest.

Harvey and McBride were both arrested and charged with open lewdness and disorderly conduct. Chitwood suspects they were surprised by the level of police interest.

“Imaging being arrested by 25 cops,” Chitwood said, according to NBC Philadelphia. “They were as shocked as the police were.”

Harvey and McBride were both released on $30,000 unsecured bail pending a preliminary hearing July 10 in district court, the Delco Times reported.
