A rapist who was caught after a CCTV camera operator phoned the police while the attack was happening has been jailed for four years in Devon.
Mukbob Ali, 24, who fled the Torquay alley where he targeted and attacked his victim, pleaded guilty to rape at Exeter Crown Court.
He was captured by the police less than 10 minutes after the attack in April.
The surveillance video footage of the midnight attack in Torquay was shown to Judge Graham Cottle in court.
He saw Ali partially strip his 32-year-old married victim, bang her head on a wall, put his hands round her throat, and order her to keep quiet while her raped her.
The rape happened after the woman had an argument with her husband and was walking back to her car.
Ali - a total stranger - followed her and attacked her in the dark alley, said prosecutor Iain Leadbetter.
He told the court the victim said after her ordeal: "My life has been ripped apart."
Defence counsel Adam Vaitilingam said Ali, of Tor Hill Road, Torquay, had expressed "sorrow and remorse".
Judge Cottle told Ali that had "targeted" his victim and raped her despite her efforts to resist.
He ordered Ali to sign on the Sex Offenders Register for life.
