A mum-to-be has told how her ex snatched her phone from her hand as she was calling the police to report him for assaulting her.
Dianne Sanderson said she tried to summon officers to her home because David Kerr "yanked" her off a couch and stamped on her head.
But Miss Sanderson, who is due to give birth in August, said he broke the phone after grabbing it from her grasp after they clashed at her home in Paisley, Renfrewshire.
Sanderson was giving evidence on the first day of Kerr's trial at Paisley Sheriff Court.
He denies the two charges he faces - assault and breaking bail conditions.
Prosecutors claim he assaulted Miss Sanderson to her injury, by grabbing her by the body, pulling her to the ground, and stamping on her head.
And he is said to have broken a bail ban on approaching or contacting her by entering her home and being with her on August 28, 2020.
Both charges are said to be aggravated by involving abuse of his ex-partner, as per Section 1 of the Abusive Behaviour and Sexual Harm (Scotland) Act 2016.
Giving evidence about the day in question, Miss Sanderson said they had argued with each other and that Kerr went on to assault her.
She explained: "I was no longer shouting and bawling when I phoned the police.
"I didn't want him to catch me on the phone. He caught me making the phone call and smashed the phone - that's how the phone call ends.
"He pulled me by the legs, the calves. He yanked me from the couch.
"I came off the couch and banged my side and banged my head. I had a lump on the side of the head.
"He stamped on my head. I had a slight lump on the right hand side of my head.
"It was a stamp. It wasn't the hardest stamp, but it was a stamp. It wasn't a full stamp."
She said she went to hospital as she developed "a really, really sore head, like a really bad migraine" after the alleged attack.
But she conceded under cross-examination from defence solicitor James Arrol that her medical records from that day stated she had a headache before the alleged assault.
And she denied claims that she had actually nearly fought with her own friends that evening and had then "phoned the police and fabricated an assault".
Miss Sanderson's downstairs neighbour, Lewis Ashe, also gave evidence, and said he heard noises coming from the flat that night.
He said: "I thought it was a fight. I didn't know who but I thought someone was having a fight.
"I thought it sounded like someone stamping on the ground. Dianne sounded like she was in distress.
"There was definitely loud banging. It was as if she was telling someone to stop during the banging.
"There were at least four or five bangs. I thought it was someone being kicked or stamped on, but I don't know who was involved apart from Dianne."
Miss Sanderson's friend, Jodie Cameron, also gave evidence.
The 25-year-old said she was in the flat on the night in question.
She said Kerr was there too and that she knew Kerr was subject to bail conditions which meant he was not to approach or contact Miss Sanderson.
Kerr has pled not guilty and the trial, before Sheriff Bruce Erroch, continues.
