Big Mags Haney's grand-daughter is facing jail after calling a sheriff "sick" and a prosecutor a speccy bi*ch.

Kim Cowan, formerly known as Kim Haney, lost her temper in the dock after she was remanded in custody at Alloa Sheriff Court, accused of an alleged theft.

As a result of the incident last year, Haney, 37, appeared in the dock at Falkirk Sheriff Court and pleaded guilty on indictment to breach of the peace.

The incident occurred on November 25, 2014, after Sheriff Donald Ferguson, at Alloa, had remanded her in custody following a Crown objection to bail by procurator fiscal depute Gail Russell.

Depute fiscal Claire Bremner told the Falkirk last Thursday (October 8) that there were a number of people on the public benches in the No. 2 court at Alloa when Haney was brought in from the cells.

Miss Bremner said: "The accused was accompanied by G4S personnel and she was double-handcuffed, as per the protocol.

"She pled not guilty. The Crown opposed bail and after hearing from the procurator fiscal depute and the accused's solicitor, the sheriff remanded her and a co-accused in custody.

"Miss Cowan interjected, 'you're remanding us?'

"She then began to shout, and directing her comments at the sheriff, she shouted 'fu*king bas*ard' and 'sick c*nt'.

"The sheriff instructed G4S to remove Miss Cowan and take her back to the cells

"She continued to shout and swear

"Police officers attempted to remove her from the dock, while the sheriff rose from the bench and retired to his chambers."

Miss Cowan then turned towards Miss Russell and shouted "I'm going to fu*king kill you, you speccy bi*ch."

She began to kick out at the dock with her feet and hit the court walls.

Miss Bremner said: "She was struggling with the officers, but no attempt was made by her to kick either the police officers or G4S personnel.

"She was thereafter removed back to the cell area."

She was cautioned and charged, and replied: "I'm sorry, but I was really shocked at getting the jail."

Miss Bremner added: "The procurator fiscal depute involved said that, though she did not show it in court, she was affected by the incident, and she was quite shaken up, and alarmed and shocked by the situation."

Virgil Crawford, defending, said Cowan, from Hillcrest Drive in Alloa, had been "concerned" at being remanded because she had a family funeral to attend.

He said: "She accepts that she vented her frustration in the dock, and she ought not to have done."

Sheriff Craig Caldwell deferred sentence for reports and - refusing bail - remanded Cowan in custody.

She will re-appear for sentence on October 29.

Cowan was deeply loyal to the late crime clan matriarch Big Mags, who died in 2013.

When Mags's Stirling-based heroin-dealer family business was busted in 2001, resulting in a 12-year jail term for Mags, then 60, Kim was called to give evidence but refused to reveal the identity of the person for whom she had peddled bags of the killer drug.

Trial judge Lady Smith held her to be in contempt of court and jailed her for two years.
