躲猫猫（死）(duǒ māomāo (sǐ)): (death by) hide-and-seek
To die in police custody under suspicious circumstances.
In 2009, farmer Li Qiaoming died while in detention for illegal logging. The prison authorities claimed that Li died of a head injury sustained while playing hide-and-seek with other inmates. Netizens balked, saying they suspected Li had instead been beaten to death by the police.
To assuage online anger, the provincial authorities called for volunteers for an inspection of the prison. Fifteen inspectors were "randomly selected" from a pool of about a thousand. The inspection backfired when the public learned that the "volunteers" were former employees of state-run media.
The "hide-and-seek incident" (躲猫猫事件 duǒ māomāo shìjiàn) now symbolizes cover-ups of police brutality.

Lizhuang (@李庄): Died in his sleep? After death by face washing, death by hide-and-seek, death by meal, and death by drinking water, now there's a new way of dying. (October 16, 2014)
