ROTTERDAM, Netherlands (AP) — Police in the Netherlands have arrested a man who locked himself in a toilet of a Thalys high-speed train heading for Paris early Friday.

Police said in tweets that the arrest happened at Rotterdam Central station without incident. No further information about the man was immediately available.

The train was evacuated as a precaution.

The incident comes less than a month after passengers subdued a gunman on board a Thalys train in northern France as it was traveling from Amsterdam to Paris.

Thalys said earlier in a tweet that, "Security forces have situation under control. No risk for our passengers."

NOS state television pictures showed heavily armed police with protective shields and equipment scanning the train cars and searching inside.

Last week, European rail operators met with interior and justice ministry officials to discuss whether to beef up train security in the European Union.

The consensus from those talks was that no disproportionate and costly security action should be taken that would hinder high-speed international rail traffic in the European Union.

This means it is unlikely that metal detectors would be installed in European stations and that passenger information would not be systematically collected.
