Quincy Green, 44, was arrested on suspicion of firearm offences in April and kept under house arrest.

But the security company that fits ankle bracelets on pre-trial detainees in Washington, DC, reportedly attached the bracelet over his sock.

In doing so, they failed to notice that he had a prosthetic leg, and he replaced it with a back-up leg to leave his house.

He was identified as a suspect in a shooting, but police were baffled when the GPS readings from his ankle bracelet showed that he was a mile away at home.

But after getting a search warrant for his home, they found the bracelet and the prosthetic leg in a box.
