The brother of a Chinese activist whose escape from house arrest last year angered authorities says harassment of his family has intensified with his wife facing possible indictment and his home being pelted with stones and dead chickens.

Legal activist Chen Guangcheng fled to the U.S. Embassy last April, setting off a diplomatic crisis. Chinese authorities later allowed him to go to the U.S.

His brother, Chen Guangfu, said Thursday that authorities in Yinan county questioned his wife on suspicion of harboring a suspect.

The brother says harassment of his family has grown in recent weeks with dead chickens being hurled into his backyard and stones cast at his house, breaking windows and roof tiles. He says posters put up in his village call his family traitors.
