Thank goodness for this law-a-riding citizen.

In a hilarious new video, a police officer in Gosport, England, rides a child’s tiny bike to catch a burglary suspect.

Officers were searching for the man in the White Lion Walk area of town Friday night when a quick-thinking cop spotted a boy on a bike and asked to borrow it during the pursuit, SWNS reported.

“Please can I borrow your bike?” Hampshire police officer Harriett Taylor asked the boy. “I will return it to you.”

The youngster agreed and watched as Taylor took off on the small bike towards the suspect.

In the video, Taylor can be seen peddling down the street on the blue-and-white bike — which is significantly smaller than her.

It looks like the off-the-chain plan worked perfectly, as the suspect was arrested on suspicion of theft, burglary and shoplifting.

Now, the boy who lent the cop the bike is being hailed by Hampshire police as a “little hero.”

“If you thought you spotted PC Taylor riding a child’s bike in the town center last night, we can confirm that your eyes weren’t deceiving you,” police said in a statement obtained by SWNS.

“She was indeed riding a child’s bike in the town center earlier this evening!”

And, true to her word, Taylor returned the bike to the boy and posed for a photo with him.

“Thank you so much for the generous loan of your bike, young man!” police applauded him. “You, and your bike, were a great help to us!”

Hampshire police also joked the youngster could borrow a police car whenever he needs one.
