A bride's wedding day was ruined after her brother was seen sniffing cocaine at the plush wedding reception before attacking one of the guests with a pint glass.
Joseph Peckham, 24, of Pontprennau, Cardiff, brought "shame" to his older sister Becky on the wedding day after a groom's relative, Matthew Oliver, warned of white powder in the luxury restaurant's men's room.
The reception went into chaos when cocaine user Peckham Oliver threw a pint glass in the garden at the expensive reception in Oldwalls on the Gower, South Wales.
Peckham's sister Becky married her long-time partner, but had "ruined" her day by her brother

A court heard that security forces were trying to get Mr. Oliver to safety – but Peckham and five other men then jumped on him.
Mr. Oliver, the groom's cousin, was taken to the hospital with a sore throat by the reception.
Prosecutor Tom Scapens said Mr. Oliver enjoyed the day until he saw Peckham on the toilet, who was using drugs.
Mr. Scapens said, "Mr. Oliver simply says that he tried to claim that a wedding is not the place where drugs are used."
Peckha is said to have "goaded" a relative of the groom all day before attacking him
The wedding reception was held at the luxurious Odlwalls venue in Gower, South Wales
He confronted him with his behavior, but was asked to get lost.
The court heard that Peckham was trying to "prick" Mr. Oliver all evening and approached him at 9:30 p.m. in the garden area.
Mr. Oliver tried to walk away to spread the situation, but was then pushed to the ground by Peckham's colleague Paul Hunter.
Swansea Crown Court heard that Peckham was seen on CCTV walking over to Mr. Oliver with a pint glass in hand.
Mr. Scapens said: & # 39; Joseph Peckham lifts the pint glass in a gesture and throws it onto Mr. Oliver's head area by force.
Oliver saw him do this and raised his hand to protect his face. At the time, he didn't know whether the glass hit him or not. & # 39;
The court heard that security personnel took Mr. Oliver to safety outside the luxurious Oldwalls venue in Gower, South Wales.
But Peckham spotted him and jumped on him on August 25 last year.
Mr. Scapens said: “Mr. Oliver hears a girl screaming and turns to see that the defendant has run towards him.
"He felt a series of blows rain on him."
Peckham pleaded guilty to serious physical harm and was sentenced to 13 months in prison
The court heard that witnesses saw five other men jumping into the fight.
Mr. Scapens said, “Security personnel have pulled this defendant away from Mr. Oliver. Mr. Oliver could then see and feel that he was bleeding from the back of his neck. & # 39;
The court heard that he was taken to the hospital with a "small irregular cut" to the left of his neck.
Peckham, who has no previous convictions, told police that the victim lied and denied throwing the glass.
However, he later pleaded guilty to serious physical injury.
The court heard that Mr. Oliver did not want to make a statement about the victim's effects.
As a defense lawyer, Adam Sharpe said that Peckham "must explain to his mother that he uses drugs" and "endure the shame and the effects".
Mr. Sharpe said, "This was completely uncharacteristic and his actions had effectively ruined his sister's wedding."
The event in Oldwalls was attended by family members on both the bride and groom's side
Peckham was a supervisor in the business run by his brother-in-law, the groom at the wedding, and "it says a lot about his job that they stand by his side."
Judge Catherine Richards told Peckham that he had acted "aggressively and sloppyly" on the day in question, although she accepted that he was really repentant for what he had done.
Judge Catherine Richards presented Peckham from Pontprennau, Cardiff with a 13-month suspended sentence.
She said, "I have no doubt that the effects of what you did at your sister's wedding would have been explained to you by others."
She ordered him to do 200 hours of unpaid work and granted Mr. Oliver £ 500 compensation.
