A man involved in a standoff with the Royal Newfoundland Constabulary in St. John's in May pleaded not guilty during a court appearance on Thursday.

Justin Wiseman, 21, is facing several weapons-related charges after a nine-hour standoff in a house on Springdale Street.

Wiseman also pleaded not guilty to robbing a nearby convenience store.

A trial for the weapons charges is set for November, and a December trial is slated for the alleged robbery.
