A TEENAGER who "heard voices" headbutted a man who went to his house to confront him, a court heard.

Benjamin Bailey's search for someone who had been taunting him that day led to the attack, likely to have been spurred by his mental health problems, Kidderminster magistrates were told.

The 19-year-old headbutted James Humphries, who went to see him after an earlier altercation, said Kiernan Cunningham, prosecuting.

Bailey had called at the home of Mr Humphries at about 4.30pm on December 14, thrown stones at a window and demanded to see Lee Kane, who he thought lived at the address.

Kane had "taunted (Bailey) throughout the day" Simon Swaffield, defending, said.

However, Bailey - who works at his family's cleaning firm - left after Mr Humphries denied he was harbouring Mr Kane, who knew Bailey from school.

However, Mr Humphries went to Bailey's Willowfield Drive home in Kidderminster later that day where the incident took place.

"Bailey said he got wound up over this and headbutted Mr Humphries," said Mr Cunnigham, referring to police interviews.

"Mr Bailey accepts he was in the wrong and he accepted he got the address mixed up and didn't mean to assault the man but was wound up that the man had come round to his house," he added.

Mr Swaffield said: "The main manifestation of Bailey's illness is he hears voices and it is perfectly possible that the impact of his condition was the genesis of this incident.

"The injuries suffered by Mr Humphries are thankfully slight - a reddening bruise above the left eyebrow."

Bailey - who pleaded guilty to assault - has been treated at Kidderminster Hospital for his condition, he added.

He was fined £75 and ordered to pay costs of £43 and £50 compensation.
