Oscar Branning (Pierre Moullier) has turned on one of his own with a knife.

As viewers of the soap know, the newbie is in hot water with some vicious thugs, after he tipped off the police about their involvement in the car robbery.

The group’s ringleader Mike (Tai Hilferink) had tried to petrol bomb Oscar’s home, mistakenly targeting the neighbours instead. As a result he was kicked out by mum Tanya (Jo Joyner) and has settled in Albert Square since being released from a youth detention centre.

So far he’s proved himself to be quite the troublemaker; trying to scam Ian Beale (Adam Woodyatt), flirting with just about every man or woman he’s crossed, and causing undue stress for his sister Lauren (Jacqueline Jossa) and her fiancé Peter Beale (Thomas Law).

After discovering that his nephew Jimmy is visually impaired, fans saw a softer side to Oscar, who later volunteered to babysit his two nephews.

Disaster struck when Mike let himself into the house, leaving a large kitchen knife jammed in the chopping board as a warning of what he was capable of.

In today’s episode, Lauren found out about the altercation. Louie, who had spotted Mike chatting with Oscar, asked if he was going to return again soon.

A troubled Oscar was then forced to explain what had happened, and promised his sister that her sons weren’t in danger.

Later, after heading to the market for a shift, he spotted Mike and his mate Harrison lurking in the shadows. Knowing that it was high time this stopped, he pulled the lads to one side and tried to find a solution.

Harrison swooped in from behind and punched him in the stomach, with Mike lifting a brick over Oscar’s head. Luckily, Jack Branning (Scott Maslen) rushed to his defence, but the violence didn’t end there.

Paranoid that the situation had been made a whole lot worse – and that it wouldn’t be long before Mike returned for the next stage of his revenge – Oscar sat in bed clutching a knife.

A suspicious noise was heard in the hallway, and a hooded figure appeared.

Oscar jumped onto them with the knife, only for the mysterious intruder to be revealed as… Peter, wearing his dressing gown.
