Teen stabbed in violent attack in Footscray
The violent mob assault that saw teen stabbed at a Footscray McDonald's is just another in a series of violent attacks in Melbourne's west.
An employee at the McDonald's said some workers were in fear after a 15-year-old boy was stabbed multiple times by a gang of as many as 20 people.
The attack happened in the Ballarat Road car park about 10.30pm on Saturday.
Minutes earlier, a 16-year-old was stabbed in the stomach and wrist outside a home in nearby Gordon Street.
The two victims remain in a stable condition in hospital.
Senior Detective Brett Van Der Vliet of the Maribyrnong Crime Investigation Unit said police were looking for numerous offenders of Asian appearance, aged in their late teens and early 20s.
"We're not sure what's occurred prior to this occurring, or why these males have all ended up in the same place.
"We can't say whether they've organised to meet here or whether it's just a chance occurrence, we're unsure at this stage.
"I would say it's unusual to have this sort of thing happen.
"The attacks are quite vicious with two males receiving stab wounds and one of those males also receiving large cuts to his leg and arm area."
A McDonald's worker said the 24-hour-store was a trouble spot, leaving some workers fearful.
"But it can happen with anyone; it doesn't matter if it's McDonald's or somewhere else," he added.
