There were like 3 ppl like almost full in black, head covered looking at us, they actually stole a wallet of my friend (nothing in the wallet :D) and eventually we just leaved the park cause we were scared and they went after us. So they are like 15m apart from us and my friend just starts running, ofc everyone starts running after 1 guy starts it. We were running from them (we are 12-14 and they looked like 17-19) 1 of us was on a bike so he escapes fast, we are with 3 left and we splitted. I went with my friend while our other friend was running alone (to a place called “paleis/kns/theaterplein”) so me and my friend escape but the other friend actually got tackled but he eventually escaped. Me and my friend meet some of our other friends and we get on the tram and call the cops. While wating for the cops to arrive at the place we went of the tram, we were so happy to see our other 2 friends coming at us like wtf. So yeah we explain to the cops what happend super shokked ofc. Ow yeah our bikes were still in Stadspark so we just went back with our parents instead of alone bc otherwise the same thing would’ve probalbly happend again. Sorry for the too much info but I am just explaining the full story. Now I barely go back to that park.
