A couple and a friend armed themselves with a glass and a wooden plank before smashing a woman's car up and attacking her family. They made threats to kill the woman after she told them she was going to ring social services.
Sinead Feneck, 28, Kyle O'Callaghan, 27, and Jordan Hull, 26, caused a "scene of violence" in Cardiff on March 23 last year when they attended the home of Zoe Hall and her family. Ms Hall had threatened to call social services on Feneck, which led to a confrontation between the two.
A sentencing hearing at Merthyr Tydfil Crown Court heard Fenck and Ms Hall bumped into each other outside a shop in Llanrumney and the defendant said: "I am going to kill you if you grass me up to social services" and threatened to throw a glass bottle at her car. She added: "Watch in the next five minutes."
