Chinese police have busted a ring of telephone scammers and arrested 32 suspects in the Philippines.

In collaboration with 125 Philippine police officers, police from Wuhan City in central China's Hubei Province raided five dens in 24 days and arrested 32 suspects, including two from the Chinese mainland.

It was the first time Wuhan police had been involved on operations overseas. They flew back to Wuhan on Tuesday morning with the two Chinese suspects in custody.

On Sep. 27, 2013, gang members called a woman from Wuhan and convinced her to transfer 1.4 million yuan (229,309 U.S. dollars) into their account. Seven days later, another woman in the city was cheated out of 1.2 million yuan in the same way, according to the police.

Police later discovered the fraud originated in the Philippines.

This kind of fraud is on the rise in China with middle-aged and elderly people the main targets.
