Dubbo mother Leanne Medcalf claims young people are running amok in the streets of Dubbo.

Mrs Medcalf is concerned about the safety of Dubbo’s youth after an incident at her son’s 18th birthday party last Saturday.

“Where are all the parents?” Mrs Medcalf asked.

Tyler Medcalf’s 18th birthday party became violent after 20 to

30 youths allegedly jumped

security fencing and gatecrashed the festivities.

“Twenty to 30 kids jumped the fence at the back of our property after being refused entry by the security guard,” she said.

“They were all obviously drunk.

“They were asked to leave but refused. It was clear they were causing trouble,” Mrs Medcalf said.

Police say the scene that followed was fuelled by alcohol.

A large number of police attended the scene in Pine Knoll Drive about 1.45am and saw a large crowd of intoxicated people on the street outside the home.

“The car sirens were used to disperse the crowd and move them on,” Orana Local Area Command crime manager Mark Meredith said.

“A person, obviously upset, was seen carrying an offensive implement.

“If police come across persons in possession of an offensive implement or weapon they will engage them to do the appropriate thing. If they don’t comply with police directions they may be subject to a burst of OC (capsicum) spray, which is what happened in this incident,” Mr Meredith said.

The man, the owner of the property, received a dose of capsicum spray for failing to comply with police commands.

A further incident occurred inside the home following the arrival of ambulance officers.

Police called ambulance officers to the scene to “decontaminate” the OC spray victim.

“The biggest problem (at the scene) was a large gathering of kids and adults suffering the effects of intoxication whereby fights broke out,” Mr Meredith said.

Both the police and Mrs Medcalf agree that text messaging and mobile phones were a key factor in the party spiralling out of control.

“Children use their mobile phones to tell others, text others, they even use the internet...to tell others that there is a party on. That is when it becomes difficult to control,” Mr Meredith said.

Mrs Medcalf agrees.

“Text messaging definitely led to the party getting out of control.

“About 100 kids were on the door list. The security guard was turning away every second person,” Mrs Medcalf said.

It is alleged that about 200 youths were spread over the back and front yards between the hours of 11pm and 2am.

Police are continuing investigations into how the incident escalated into violence.
