When a peace officer has stopped a person for questioning pursuant to this section and reasonably suspects he is in danger of life or limb, he may search such person for a dangerous weapon. If the peace officer finds such a weapon or any other thing the possession of which may constitute a crime, he may take and keep it until the completion of questioning, at which time he shall either return it, if lawfully possessed, or arrest such person. For purposes of this section, peace officer shall include credentialed conservation officers of the Game and Parks Commission.
