During a prison riot, the defendant obtained a metal fence post, some five or six feet in length. Wielding it as a club, he attempted to strike a guard. He then hurled it as a javelin, striking the guard in the chest.

We think it permissible to find the length of metal pipe, used as it was, a dangerous weapon. We find no infirmity in the conviction of the defendant for assault with a dangerous weapon.

Affirmed.
