BEIJING - The family of a boy killed in a subway escalator accident is considering legal action as negotiations over compensation stall.

Wu Shibo, 13, died and 30 other people were injured last Tuesday when a malfunction caused a rising escalator at the Beijing Zoo station on Line 4 to reverse.

The boy's father, Wu Conglin, who was among those injured, has demanded 1.2 million yuan ($185,615) from Beijing MTR Corp, which operates the line.
