I found that picture in the newspaper last Friday but unfortunately could not find the online version on DN.se.
Tommy Åberg was riding his bike on Blekingegatan (south of Stockholm) when he came to a police car parked on the bike lane. He thought something wrong was going on (like a robbery) at first and decided to have a quick look around. But the emergency seems to have been of a completely different nature: the law enforcers needed a little sugar kick and were just buying some candies.
