A woman jointly accused of murdering a man for cocaine and cash told a jury he was "a very nice guy" who would take her for a milkshake.

Carla Callum, 30, said she would never have hurt Ahsanuallah Nawazai, whom she knew as Marshall.

Carla Callum, of Walsingham Way, London Colney, and Anis Anderson, 20, of Fordwych Road, Cricklewood, are alleged to have lured Ahsanullah Nawazai to London Colney on the evening of November 28, 2018, when he was stabbed to death.

Both deny murder.

Giving evidence at her trial at St Albans crown court, Callum was asked by her barrister Tim Clark QC: "Did you intend any harm to come to him?"

She replied: "No, I never."

Murder trial underway after stabbing in London Colney

Ms Callum, who said she had been diagnosed with depression and anxiety, said she had bought drugs from 20-year-old Mr Nawazai, who was from Walthamstow, for six or seven months, maybe longer.

She went on: "He was a very nice guy. He would take me for a milkshake."

She said she met her co-defendant Anis Anderson, whom she knew as J, through other drug users. He had lived at her home since April 2018.

The jury has heard that when Mr Nawazai supplied Ms Callum with drugs earlier that day, she had left her phone in his Nissan Qashqai car.

When he returned to Walsingham Way, he was attacked in the car while he was still wearing a seat belt.

He managed to get out and was found collapsed and bleeding in the street outside St Bernadette Catholic Primary School at 7.13pm by a jogger, who called for an ambulance.

He was taken to Watford General Hospital, where he died.

Prosecutor Steven Perian QC said Mr Nawazai was found shortly before 19.13 collapsed in front of the school entrance. "He was wearing a T shirt, jeans, white socks, but no shoes. He had a £20 crumpled note which was half hanging out of his jeans' pocket."

A post-mortem examination revealed that Mr Nawazai, from Walthamstow, suffered a number of stab injuries caused by a bladed weapon, including a fatal stab wound to the chest.

Continuing her evidence, Ms Callum said that since April last year her co-defendant had lived with her. She claimed he sold crack cocaine and heroin.

Under cross-examination by Anthony Berry QC she denied telling Anderson to rob someone.

She said Mr Nawazai had not asked her to leave her phone in his car as a deposit for drugs. She replied: "Marshall wasn't like that - that wasn't him."

Mr Berry said: "Because of your urgent need for drugs you suggested you wanted him to rob your dealer?" She replied: "That is absolute nonsense."

Ms Callum denied she had put a knife in her co-defendant's top pocket and handed him a pair of gloves.

The case continues.
