The Central Finland Police Department is investigating an alleged 'needle spiking' attack that took place at the Blockfest festival in Tampere.
The victim told police they had gotten into an argument with a stranger at the festival drinking area. Shortly after, they reported feeling a sting on their upper left arm.
After getting checked by paramedics at the emergency tent, the victim continued their evening at the festival.
Police said they are investigating the case as assault and are not currently providing any further details.
A wider phenomenon
Several 'needle spiking' attacks have been reported in central Europe over the last two years.
Additionally, more than 1,300 incidents of the phenomenon were reported across the UK over the past six months.
According to French police in June, 300 people, mostly women, have been injected at nightclubs and concerts in France. A number of the victims had obvious signs of having been stabbed by a needle, such as bruising on their skin. Additionally, they reported feeling unwell.
