Chinese police have arrested seven people suspected of involvement in an attack and bombing at a train station last month in the western city of Urumqi, the Global Times newspaper reported Saturday.

Three people were killed, including the assailants, and 79 wounded in the bombing and knife attack on April 30 at a station in Urumqi, the capital of China's far-west Xinjiang region, as President Xi Jinping was wrapping up a visit to the area.

The Global Times said police caught seven people at a farm in Changji and ID'd them as including two brothers, a cousin and wife of one of the assailants who was killed. The suspects were being investigated, the paper said.

Xinjiang authorities earlier identified the assailant as Sedierding Shawuti, a 39-year-old man from Xayar County in Xinjiang's Aksu region. His name could identify him as possible member of the Muslim Uighur minority.
