A ROYAL wedding street party was ruined after being hijacked by gatecrashers, police have said.

The party was one of three in Suffolk which led to officers being called in due to anti-social behaviour and violence.

Residents in Wolsey Street, Stowmarket, had planned to mark the wedding by holding a celebration on the green nearby.

However, police said the atmosphere was spoiled when people arrived to rig up music speakers after invitations had been sent out on a social networking site.

Police spokeswoman Lisa McGrann said officers began to receive complaints of loud noise just after 2pm on Friday.

Multiple calls were then said to have been made by irate residents throughout the day, as the noise continued to blast out from the music system’s speakers.

Complaints were also made about anti-social behaviour.

Police continued to monitor the area, but more officers had to be drafted in as the day progressed. At one stage riot-trained officers were sent, although Mrs McGrann said it did not appear that they were ultimately required.

The disturbance is understood to have ended when the speakers blew up at about 7pm.

Police discovered an open invitation had been posted on Facebook, with many people arriving from outside the area.

Four people, including a teenage girl, were spoken to by officers relating to drug offences.

The 15-year-old girl was reprimanded for possession of ketamine, a Class C drug. A 20-year-old woman received a caution for the same offence, while a 21-year-old man was also cautioned for possessing a Class C drug.

A 21-year-old man from Haverhill must report back to police after he was also spoken to about possession of a Class C drug.

Elsewhere, police were called to Leiston Road in Haverhill when a fight broke out and a bottle was used to smash a car windscreen, near the Suffolk Punch pub, during another Royal wedding street party.

Although paramedics and police officer were sent to the scene shortly after 9.20pm on Friday, the people who had been involved in the disturbance had dispersed by the time the emergency services arrived and no one was taken to hospital.

In Ipswich, up to 50 people were said to have been involved in fights and anti-social behaviour throughout the day in the Hawke Road area.

Vehicles were damaged, including a police car which had its windscreen screen smashed.
