German police have arrested a man they suspect of being the mastermind of an armed raid on a poker¹ tournament in Berlin.

德国警方逮捕一名男子，该男子涉嫌策划在柏林扑克锦标赛上进行武装抢劫。

The heavily-armed gang made off with the tournament jackpot（累积赌注，头奖） of 242,000 euros ($327,000; £217,000) in early March.

Police said a 28-year-old Lebanese man, the fourth arrested in connection with（与……有关） the raid, had been detained on Sunday.

In a statement, authorities described the man as "the brains behind the operation".

"According to the current state of our investigation², the suspect is thought to have been the organiser [...] He also drove the getaway（逃跑用的） car," a black Mercedes-Benz, Berlin police said in a statement.

Two other suspects were arrested earlier this week and a third on Saturday morning at Berlin's Tegel airport, the Associated Press news agency reports.

On 6 March, the gang of four - reportedly carrying handguns - burst into Berlin's Hyatt hotel in the city's Potsdamer Platz.

To the shock of the poker players taking part in the tournament, they made off with the jackpot in bags of cash, whose initial sum was reported to be far higher.
