In North Rhine-Westphalia, shots were fired twice within a few hours after ATMs were blown up.
Early Friday morning, several men blew up a cash dispenser in Ibbenbüren, Münsterland.
Police officers tried to block their way at a nearby entrance to Autobahn 30 in the direction of the Netherlands.
When the perpetrators made a beeline for a police officer, he jumped to the side and fired several shots at the getaway vehicle, which was speeding away in the direction of Amsterdam.

A good 24 hours earlier, a patrol car crew had surprised three perpetrators after blowing up an ATM in a Sparkasse branch in Castrop-Rauxel.
According to previous knowledge, there was an exchange of gunfire.
While officers were unharmed, one of the suspects was hit by a police bullet and taken to a hospital.
There was no danger to life.
The other two men were able to escape in a highly powered getaway vehicle, which was later found in a wooded area not far away.
Because the number of explosive attacks has increased sharply in recent months, the North Rhine-Westphalian security authorities are trying to change their strategy.
Since February, every available patrol car has been on the street at night - which, as in Castrop-Rauxel, has repeatedly led to perpetrators being caught red-handed.
For a few weeks now, the special commission "Begas" has been in place in the Ministry of the Interior, which not only analyzes what needs to be improved in investigations, searches and - together with the financial institutions - in prevention, but is also intended to improve cooperation with the Dutch authorities.
Because, as the two cases from Ibbenbüren and Castrop-Rauxel make clear, a large proportion of the unscrupulous demolition gangs still come from Holland.
