SHENYANG -- A local legislator and four members of his family have been detained for alleged illegal fundraising of over one hundred million yuan, in Northeast China's Liaoning province.

Ma Deqiang, a deputy to the people's congress of Tieling city, and his wife Cheng Hong, legal representative of a pawn company in the city's Xifeng county, were arrested on Dec 13, according to sources with the county publicity department.

Cheng raised almost 110 million yuan (about $18 million) from more than 400 people, promising them high interest rates, but had not paid principal or interest since July 2013, the sources said.

Ma's son, daughter, and daughter-in-law were also detained. Both Ma's son and daughter work for the county government.

Police have seized 25 houses, 1.97 million yuan in cash, along with gold, antiques and jewels.
