TERRORIST Khalid Masood was a party animal who loved marathon crack sessions with hookers, a pal revealed last night.

Masood, 52, went on drug binges for 72 hours at a time — then robbed pushers at knifepoint for his next fix.

The Islamic fanatic — then plain Adrian Elms — also blew thousands on hookers while staying at a rented pad and on pals’ sofas.

His vice obsession in the early 2000s saw landlady Cassie Havard, 43, and mates kick him out.

Cassie revealed he often got violent after benders on everything from crack cocaine to acid.

She said: “He wasn’t a proper Muslim. He s*****d prostitutes, smoked copious amounts of crack and stuck knives in people’s faces.

“He was a madman. After one four-day crack session, one druggie pal got paranoid and accused him of being an undercover cop.

“Adrian went absolutely wild and ran to the kitchen to grab the biggest knife he could find.

“He went back in the room and slashed the guy’s face to pieces.

“It was horrific, but he always had that darker side about him.”

Masood posed as an ardent Muslim, once threatening to kill a female friend at a party after a joke about religion and heaven with Islam as the punchline.

But other pals fear he may have been high on booze and drugs during his terror rampage.

One said: “He would take anything, from coke and ecstasy to acid and crack, which he would get through like a steam train.

“When high his mood dominated everything in a nasty way.

“You would be put in your place with a terrifying glare.

“He would start a fight or slam tables demanding to know where his cigarettes were, just to make sure he was centre stage.

“As soon as the picture of the terrorist on a stretcher outside Parliament was published, we suspected it was him.

"It was the last act of a man who spent most of his life terrorising others.”

Masood also used drugs to fuel his party lifestyle in Eastbourne, East Sussex.

The friend added: “He went to clubs and raves but mainly house parties. He was a party animal.

“While on ecstasy he would go on for hours. But while winding down he would get a joint and listen to Bob Marley.”

Masood lived in Northiam, East Sussex, in the late 1990s.

He moved to nearby Eastbourne after splitting from businesswoman wife Jane Harvey.

He claimed to be a labourer. But pals say he made a living thieving fishing boats.

The crook would sail them to France and flog the fishing licences before returning to the UK and dumping them.

One friend revealed: “He did that for years in Eastbourne and must have made £100,000.

“Sometimes he returned the boats to where he found them. At other times he would simply abandon them.

“He didn’t need to do it. He was a bright guy who told us how good his previous job was in London before he came to Sussex.”

One of the few things to bring out his softer side was his two kids.

A pal said: “He adored them. His eyes changed.

“It makes you wonder, if someone’s got that love and understanding, how can they kill?”

However, his tendency for aggression was never far away.

The friend added: “He was very strange about what he ate. Once, someone put bread in the toaster for him and he went berserk, shouting that it was ruined.

“Another time, he gave me a snooker cue. Something had happened at a snooker club and he told me to hide it or get rid of it.

“I didn’t want to touch it. But I was never sure if he had hurt someone, or whether it was his crack-fuelled paranoia that was sending him loopy.”

9 Attacked... Danny Smith met Masood back in 2003

Masood quit Eastbourne in 2004 — a year after he left jail over a brawl in which he knifed scaffolder Danny Smith in the face.

Meanwhile, a former housemate told how the maniac was radicalised while spending hours online at his Birmingham home in 2012.

Masood lived in the pad with his wife and a daughter and rented the student a room.

The pad is just 200 yards from two addresses that police raided over his Westminster terror attack.

The ex-housemate wept as he recalled: “He never got off his computer and never let anyone look at it. He was addicted to it.

“He had a small room downstairs. There were often Arab guys coming in and out.

“I confronted him after I got suspicious.

"But he claimed they were paying him £8,000 a time to write their university theses.

“At the time I believed him but looking back maybe he was plotting something.

"I feel sick I didn’t realise the man he was.”

Masood would also plead with his housemate to pray with him in a bid to convert him to Islam.

The man recalled: “He often talked to me about Islam and said I should take that path.

“I would meet him at 6am in the kitchen. He had a friendly smile and always said, ‘Good morning, my friend. Are you going to pray with me?’”

He also revealed Masood’s strict routine of breakfast of eggs on toast, prayers and press-ups.

The man said: “He was a fitness fanatic, always working out in front of me. He would do hundreds of press-ups a day.

“He had a powerful physique and was proud of how he looked.”

And he said of Masood’s relationship with his partner: “It was a traditional Muslim one.

“She was friendly to me but he was very much in charge. But he was loving to his daughter.

“I never heard him raise his voice.”

The man voluntarily went to police this week to reveal his association with Masood.

He added: “When I found out about the London terror attacks, I felt sick. I thought of his children. How could he do that to them?

“It worries me that I shared a house with him and had no idea what he was going to do. I feel so much anger towards him.”
