A gunman who holed up in a McDonald's in what police assumed was a hostage standoff actually hid his gun in a bathroom, lay on the floor with 20 others inside and threatened no one, authorities say.

Prosecutors said Wednesday they won't press for hostage-taking charges against Douglas Edward Girard, 32."There was no crime, period, inside McDonald's," said Sandi Gibbons, spokeswoman for the district attorney's office.

Police had assumed the worst Monday when a gunman fled into the fast-food restaurant moments after a robbery of about $200 at a clothing store nearby.

Police originally alleged Girard held McDonald's customers and employees hostage for nearly seven hours. The wait ended early Tuesday when officers lobbed "flash-bang" grenades inside and wrestled Girard to the ground.
