Four members of the same family have been arrested after a nine-year-old boy was beaten to death at his home in the eastern French city of Mulhouse.

在法国东部城市米路斯一名9岁男孩被家人暴打至死之后，警方已将该家庭的4名成员逮捕。

Police sources told local media that the boy had refused to do his homework and was hit with a broom handle.

警方消息人士向当地媒体透露，这名男孩是因为不写作业而被家人用扫帚暴打。

The boy's elder brother, sister and stepsister were all present at the time of the incident.

事发时，该男孩的姐姐、哥哥和哥哥的女友都在现场。

Although his mother was not there, she too has been arrested and was aware of what was going on, reports say.

报道指出，男孩的母亲当时虽未在现场，但因对整个家暴过程皆知情也遭到了逮捕。

But the family's initial accounts of what had happened and the ensuing post-mortem examination prompted police to continue their investigation.

这家人对所事件发生的最初描述以及随后的尸检，使得警方决定继续展开调查。

Bruises were discovered on the boy's body, particularly on his feet, according to Alsace website DNA.

据阿尔萨斯网站DNA称，在男孩身上发现了瘀伤，尤其是在他的脚上。

Although he had suffered a cardiac arrest, pathologists said the cause of death had been the blows he had suffered, DNA reported.

据DNA报道，虽然该男孩是死于心脏骤停，但病理学家表示，心脏骤停正是由于此次家暴所致。
