It is business as usual at Paris Nord station, where trains from Brussels arrive, but there is one difference: police officers from Latvia are now patrolling the station. They are helping to maintain public order during the Olympic Games and, together with their French counterparts, are patrolling the major train stations.
"The level of risk is much higher than in Latvia - and we need to be aware of that. So they take it very seriously and keep a very close eye on our colleagues too. So hopefully it will be without any major adventures," says Māris Vitkovskis, liaison officer of the State Police.
However, it is not easy to get along with their French colleagues because of the language barrier - the French do not speak English.
"Yes, unfortunately. The colleagues who monitor public order outside Paris had the same problem, that there was an English language barrier and they had to communicate with Google translate," says Vitkovskis.
Latvian police officers patrol the long routes of French trains and experience a colorful daily routine of aggressive behavior, drug use and train hoppers. So far, there have been no targeted attacks.
There are now around 30,000 police officers of various nationalities in Paris.
"When we first arrived here, it seemed that there might be more police officers at one intersection than at a good Latvian administration or police station," adds Vitkovskis.
The French are assisted by Latvian canine officers - three from the State Border Guard and two from the Military Police.
Redžijs, a Belgian Shepherd, is also full of energy after a long day of inspecting huge sports stadiums before competitions, looking for hidden explosives.
"We also work in bulletproof vests, because there was an incident where a soldier was stabbed. Our routine is from 5 a.m. to 5 p.m.," says Jānis Rozenfelds, a sergeant with the National Armed Forces (NBS) Military Police.
The other military police dog, Džeks, is calm and poses like a true professional.
"Džeks is doing quite well. Of course, there were all kinds of challenges - there were a lot of rats running and jumping out of the bushes. Then there were moments when [the dog] got scared and, of course, wanted to catch them. But he coped with his tasks very well," said NBS Military Police Corporal Matīss Bincis.
The size of the venues and stadiums to be inspected here cannot be compared with Latvia, the canine handlers say - there is much more work.
Latvians also had to check the tennis courts before Alona Ostapenko's match and the Louvre Museum before the national leaders entered.
"If we find something with the dog, we automatically call the sappers and they inspect the object. But the dogs walked through everything, paid no attention to anything, everything was very beautiful," says Major Sergejs Zeļenovskis, Head of the Canine Department of the Border Control and Immigration Service of the State Border Guard Service in Viļaka.
So the dogs are shown the Louvre. "Yes, of course, not only shown, but also at the end, when we had finished our work, we took little selfies," adds Zeļenovskis.
