and made off into France with several hundred thousand Swiss francs in the early hours
of Sunday morning, police said. The men, dressed in black clothes and black ski masks,
split into two groups during the raid on the Grand Casino Basel, Chief Inspector Peter
Gill told CNN. One group tried to break into the casino's vault on the lower level
but could not get in, but they did rob the cashier of the money that was not secured,
he said. The second group of armed robbers entered the upper level where the roulette
and blackjack tables are located and robbed the cashier there, he said. As the thieves
were leaving the casino, a woman driving by and unaware of what was occurring unknowingly
blocked the armed robbers' vehicles. A gunman pulled the woman from her vehicle, beat
her, and took off for the French border. The other gunmen followed into France, which
is only about 100 meters (yards) from the casino, Gill said. There were about 600 people
in the casino at the time of the robbery. There were no serious injuries, although one
guest on the Casino floor was kicked in the head by one of the robbers when he moved,
the police officer said. Swiss authorities are working closely with French authorities,
Gill said. The robbers spoke French and drove vehicles with French lRicense plates.
