"Attention - a band of robbers is on the run. We need a roadblock at the main road immediately," the police officer calls via the walkie-talkie.
"No problem, we'll take care of it," the two colleagues on the spot answer. They put up barrier, stop sign, traffic cone and roll out the nail strip.
Of course the police dog as backup is also let out of the dog crate. "No one will pass this roadblock," the two officers are satisfied.
