Police in north-west China have detained the daughter of a suicide bomber who blew up a bus this month, killing five people and injuring 24.  The explosion occurred on the evening of 5 January on a long-distance bus carrying 47 passengers in Pucheng county, Shaanxi province, according to Xinhua, China's official newswire. Police quickly identified one of the blast's casualties as its perpetrator, a 45-year-old local farmer named Dang Zhaofei.  On Monday, they detained his daughter as a "major suspect involved in the case", Xinhua reported, without revealing details about her role in it. Pictures online showed the turquoise bus sitting on a broad road with its windows blown out, surrounded by detritus.  The bombing was probably an expression of despondency, state media reported. Dang's life went off the rails when his son drowned in July 2008 – he was heavily in debt from operating a fruit wholesale business, and his relationship with his wife had begun to sour, it was reported. Dang's wife was on the bus with him when the bomb exploded, but she was not included on an official list of injured passengers, according to the state-run Global Times newspaper.  In an unrelated incident, an explosion tore through an underground gambling den in south-west China's Guizhou province on Monday afternoon, killing 15 people and injuring another eight. According to state media, the illegal casino was located in a makeshift tent halfway up a desolate hillside in Laoshan Village, a remote corner of county-level Kaili city in one of the country's poorest areas. The survivors were in stable condition, state media reported on Tuesday.  Eight suspects were detained, three of whom turned themselves in, the Guizhou police department announced via its official microblog account. The Kaili propaganda department said the blast was being treated as a criminal case.  According to an investigation by the independent newspaper Beijing Youth Daily, the casino opened only one or two months ago – it was originally located near the village, but soon moved far up the hillside. Villagers began spotting BMWs and other luxury cars with out-of-town licence plates parked in the hill's vicinity. Gamblers inside played Gundilong, a game that involves three dice and a large box.  Li Long, a villager in Longyang township, told the newspaper that on the afternoon of 13 January, she was taking a nap in her home 1.2 miles (2km) from the village when she heard a loud noise. Soon afterwards, the town filled with police cars and sobbing relatives of the deceased. In a nearby hospital, Li witnessed wounded victims telling doctors that they had been in a car crash, ostensibly to dissociate themselves from the incident.  "My husband called and said he was dying and had been blinded," Pan Shasha, the wife of a 26-year-old victim whose eyes were injured in the blast, told Xinhua. "He said: 'I have only my last breath,' and he asked me to take care of our child."
