A man who executed a “predatory and calculated” assault on a 13-year-old girl in a south London alley has been sentenced to seven years in prison.

The Metropolitan Police reported that Sorosh Amini, 21, pursued the girl “in broad daylight” on North End Road in Croydon last August, attempting to force drugs upon her before committing the sexual assault.

On Friday, Amini was sentenced at Croydon Crown Court after being found guilty of rape and sexual assault. In addition to his prison term, he received a 10-year sexual harm prevention order.

Detective Inspector Donnett Oseni, who oversaw the investigation, remarked: “Amini’s act against this vulnerable young girl was both predatory and premeditated. He has proven himself to be a dangerous sexual offender, and this sentence will ensure he cannot inflict harm on anyone else.”

Det Insp Oseni praised the victim for her bravery in coming forward to report the crime. “I hope today’s outcome provides her and her family with some measure of closure,” he stated.

According to the Metropolitan Police, Amini “relentlessly attempted to engage her in conversation and would not leave her be, trailing her down North End Road and into an alley.” He then forcibly kissed her and attempted to place a cannabis joint in her mouth. He also made threats by stating he was acquainted with someone involved in a recent stabbing nearby, instilling fear in the victim that he may be armed. Following this, he raped her.

After the assault, Amini left for Liverpool the next day, but police were able to track him down using mobile phone data and CCTV footage, resulting in his arrest five days later.

Amini was convicted after a two-week trial held in January.
