BERLIN, July 12 (Xinhua) -- Up to 300 German police officers were deployed on Wednesday for raids over the robbery of a 100 kg gold coin from Berlin's Bode Museum in March.

Police searched two apartments and a jeweler's store in Berlin's Neukoelln district. Two suspects were arrested with investigations currently ongoing.

There was a strong indication that the two suspects were the persons seen on the videos of the security cameras, a Berlin police representative said.

German newspaper Welt reports that the suspects are members of a large Arab family known to the police.

According to the police representative, there was first evidence that the coin, named "Big Maple Leaf" could have been melted down in the jeweler's store that was searched.

The Berlin police did not release a statement as to the whereabouts of the gold coin at this time.

The Canadian coin with the picture of Queen Elizabeth II has a face value of 1 million U.S. dollars. The gold value is around 4.2 million dollars. It was loaned to the Bode Museum in December 2010 by a private individual.

The robbery in March created an international stir. The three men, who were dressed in black and with faces hidden by hoods, accessed the museum at night with a ladder. How the men transported the giant coin unnoticed remains unclear.
