A TEENAGER has spoken out over her sexual assault after at least 35 teenage girls were attacked by a mob of 'foreign youths' at a Swedish music festival.

Alexandra Larsson, 17, was at the ‘Party in the Park’ music festival in Karlstad, about 250 miles from Stockholm over the weekend, when she became just one of the targets in the horrific number of assaults.

Girls between 12 and 17-years-old were targeted during the festival with more than 35 complaints made to police.

Waiving her right to anonymity, Ms Larsson said someone needed to speak out to draw attention to the issue.

The young woman said she was at the festival, listening to John de Sohn, when she was groped on Friday night.

She told MailOnline: “Someone took the liberty of grabbing my butt really hard. I turned away and said to the group of boys behind us that this was not okay, but I did not know who had done it. After a while, I felt someone running his fingers between my legs touching my genitals.

“I turned around and screamed right out that ‘whoever it was - you're a pig!’ I told my friends what had just happened and they were all shocked. Me and my girlfriends decided to leave the concert."

She said she felt lucky that she was wearing jeans at the time of the attack.

Authorities now fear the 35 reports of sexual assaults are just the tip of the iceberg.

Ms Larsson said she believed the young men involved in the attack were foreigners, adding that they "were probably immigrants".

Local police said that the males would be questioned in the coming week with extra staff organised for the remainder of the festival.

Two males have since been arrested on suspicion of sexual assault, with it understood they were between 15 to 17-years-old.

One tactic understood to be used during the festival includes several males surrounding a woman and assaulting her, leaving her with no escape, before dispersing into the crowd.

Ms Larsson said there was also verbal abuse thrown around during the festival, including threats to kill.

The young woman said: “It was creepy. Someone stood around me and groped me and I had no idea who it was. It was sick."

She said she felt powerless, particularly as she saw other young women leave the crowd crying after similar circumstances.

The incident has since been reported to police.

Ms Larsson said she was worried for younger victims of sexual assault as they may not be able to cope with the incident.

She said she would never visit the festival again.

Up to 24 reports of alleged assaults took place during the festival, known as Putte i Parken festival in Swedish, with another 11 reported afterwards, according to Breitbart.

A mother of a girl who was sexually assaulted at the festival also spoke out, saying her 15-year-old daughter had been humped from behind.

Speaking to The Expressen, the horrified mother said her daughter did not feel like she had been taken seriously by the guards.

Festival organisers released a statement, saying they felt deeply for those who had their experience ruined.

The statement said: "Together with police, security guards and our security guards, we are working very hard at 'Party in the Park' to make it as safe as possible."

Live Music Sweden also released a statement through the Party in the Park Facebook page over the weekend, saying they worked hard to ensure the festival was a safe place.

The statement said: "Live music is one of the best there is. A good concert where you get together with other people to share a great experience may cause your body to bubble and create feelings of community and euphoria.

"Unfortunately, we are aware that many people on a small surface can also create problems. This is why we have worked as one to prevent all forms of sexual assaults and make Swedish music festivals as safe and secure as possible."

The statement also said: "Unfortunately, it isn't so easy to solve sexual crimes and it is not a problem that is unique to festivals.

"On the contrary, we live in a society where we teach our children to treat women as objects... in order to change this situation it requires work across the board."

The Party in the Park festival attracted more than 20,000 visitors every day between Thursday and Saturday with the majority of the crowd made up of teenagers.
