The 78-year-old geezer who stabbed a burglar to death won’t face criminal charges, police announced Friday.

Richard Osborn-Brooks was cleared of any wrongdoing in the frightening home invasion Wednesday night following a police investigation, according to the Telegraph.

“This is a tragic case for all of those involved. As expected with any incident where someone has lost their life, my officers carried out a thorough investigation into the circumstances of the death,” Metropolitan Police Detective Chief Inspector Simon Harding said. “… At present — on the evidence available — we will not seek a charging decision. Therefore, no further action will be taken against the man.”

The scrappy senior citizen tussled with robber Henry Vincent, who had broken into Osborn-Brooks’ Hither Green home in southeast London. Osborn-Brooks stabbed Vincent, 37, with a screwdriver and the career criminal fled, only to be found on a road near the home. He died a few hours later at a hospital.

Osborn-Brooks, whose wife has dementia, initially was arrested on suspicion of murder charges, sparking outrage — but was released by police.

“Whilst there might be various forms of debate about which processes should be used in cases such as this, it was important that the resident was interviewed by officers under the appropriate legislation of the Police and Criminal Evidence Act; not only for the integrity of our investigation but also so that his personal and legal rights were protected,” Harding said.

He said an inquest will be conducted into the circumstances behind Vincent’s death.

Vincent, a father of three girls from Kent, had targeted senior citizens before as part of a family gang.
