Two men were stabbed at Britain's Parklife Weekender music festival on Saturday (07Jun14).
The two festival-goers were allegedly knifed during a brawl at the event in Manchester, England, according to Britain's Manchester Evening News.
One man was taken to hospital with serious but non-life threatening injuries and a second was treated at the site.
Three other revellers were injured in a separate incident at the festival, which features performances from Snoop Dogg, A$AP Rocky and Rudimental.
Two men were arrested in connection with the violence after police were called to the festival site.
Greater Manchester Police (Gmp) Chief Inspector Gary Simpson says, "There have been a few isolated incidents at Parklife Weekender Festival which we believe have involved a weapon and have caused injuries to five men. As a result, Gmp have instigated an investigation which has resulted in two men being arrested at the venue."
