A cage fighter stabbed his beautician ex-girlfriend to death after allegedly accusing her of being an escort who had slept with his family, a court heard.

Andrew Wadsworth, 37, is said to have subjected Melissa Belshaw, 32, to a "prolonged, remorseless attack" following a cocaine and alcohol binge, before rampaging outside to knife a stranger.

Texts had shown him accuse her of being an escort and having sexual relations with people he knew, including members of his family.

Wadsworth also allegedly threatened to kill the victim's 13-year-old daughter with a knife to her throat before a passer-by heard her cries of distress, smashing open the front door to rescue her.

The teenager had earlier bravely raised the alarm by calling police from inside the property before her phone battery ran out.

Wadsworth allegedly came out of the house in Wigan, Lancashire, and pinned a neighbour to the floor before repeatedly stabbing him, Manchester Crown Court heard.

Prosecutor Tim Storrie QC said only the arrival of police saved the man's life as the defendant surrendered when an officer deployed a Taser.

Melissa was pronounced dead at the scene on May 20 of this year.

The defendant claims he stabbed Melissa after losing his temper

A post-mortem examination revealed the victim sustained a series of "devastating" stab wounds delivered with severe force.

Mr Storrie said Wadsworth and Melissa had rowed the night before at her home after taking cocaine and drinking alcohol.

Their relationship was described by the prosecution as "volatile and dependent on a mutual or common interest in drink, drugs and sex".

Mr Storrie said: "It is plain from messages exchanged between the two that at times Melissa Belshaw regretted the relationship had ended but it is also plain the defendant had strong and mixed feelings about her.

"In particular, you may think the defendant was magnetically attracted to Melissa Belshaw, her lifestyle, her use of cocaine, but at the same time, he could not make her submit to his will.

"The messages also establish he was suspicious of Melissa Belshaw. He believed she worked as an escort and for some time he believed she had been involved in sexual encounters with numbers of people, some of whom he knew, including members of her family.

"And he did not believe her when she denied the suggestions he made to her."

Wadsworth admits killing Melissa but denies murder. He claimed in police interviews he lost his temper and stabbed her after she made "shock" disclosures about her sex life, and a set-up arranged by her in which he was robbed and injured.

He also denies attempted murder and making a threat to kill. The trial continues.
