A British man who deliberately drove a van into a group of Muslim worshippers near a London mosque last June, leaving one dead and injuring many more, was on Friday sentenced to life in prison with a minimum 43-year term. Darren Osborne, 48, from the Welsh capital Cardiff, was found guilty of murdering 51-year-old Makram Ali and trying to kill others in the Finsbury Park area of north London in the June 19 attack. “This was a terrorist attack. You intended to kill,” said judge Bobbie Cheema-Grubb, sentencing him at London’s Woolwich Crown Court. She said he would pose a risk to the public “perhaps for the rest of your life”. She added that he had been "rapidly radicalized" and that his "mindset became one of malevolent hatred". "In short you allowed your mind to be poisoned by those who claimed to be leaders." Osborne became radicalized over a month last year after watching a television program about a child sex ring scandal involving a gang of mainly Muslim men in northern England. The unemployed "loner" had pleaded not guilty, telling the court that a man called "Dave" was driving at the time -- a claim police denounced as a fabrication. The May Manchester suicide bombing and the June London Bridge van attack and stabbing rampage further fueled his obsession. Witnesses recalled Osborne saying: "Ive done my job, you can kill me now" and "at least I had a proper go" in the immediate aftermath of the attack. After two weeks of evidence, the jury took one hour on Thursday to find him guilty. Osborne had watched a BBC television drama which told the story of three victims of the child abuse ring, and quickly grew angry at what he deemed as inaction over the scandal, the court heard. The May Manchester suicide bombing and the June London Bridge van attack and stabbing rampage further fueled his obsession, the court was told. Osborne began researching far-right material online, police said. On June 18 last year, Osborne drove up from the Welsh capital Cardiff to central London in a hired van with the intent of attacking a pro-Palestinian march. He told the jury he had wanted to kill socialist opposition Labor leader Jeremy Corbyn and London’s Muslim mayor Sadiq Khan. Thwarted by road closures, he sought out other targets, eventually arriving hours later in Finsbury Park where he came across a group of Muslims tending to Ali who had collapsed in the street near his home after attending Ramadan prayers. Shortly after midnight, he drove at them, killing Ali. He later told the court he had tried to kill as many as possible. “Our father, like the victims of most terrorism, was entirely innocent which makes his death in this violent way all the more hurtful and we cannot imagine the trauma he felt in the last few minutes,” said Ruzina Akhtar, one of Bangladeshi-born Ali’s six children.
