The first major crime in the area was the robbery of the Prince Albert mail on July 17, 1886 near Humboldt. The first excited reports stated that six masked men had done the robbery but on further investigation it was discovered to be the work of one man.

On August 18, the mail driver identified the highwayman in Prince Albert and he was subsequently arrested and sentenced to 14 years imprisonment.

By 1904 after 30 years of service the Mounties had become a legend throughout the land and King Edward VII added the title royal to their name making it the Royal North West Mounted Police; in 1887 the detachment in the Humboldt area was closed and did not reopen until 1905 when one constable was stationed here.

The following information is taken from the Humboldt RCMP history files in Regina.

On February 28, 1907, Mr. A. Henry gave a report to Constable Smith of Humboldt of a missing farmer named Coarson. He was found frozen to death in an empty shack on March 4.

Two local chiropractors in Humboldt were accused of the murder

On May 15, 1916 after an investigation by Sgt. William Gray two horse thieves were sentenced in Humboldt to one year of hard labor.

John Adams was employed by the town to patrol Humboldt while Sgt. William Gray patrolled a large area including Wadena, Lockwood, Prud'homme and Cudworth.

The early enforcement officers had to deal with horse thieves, home brew hideouts and even chicken stealing.

The Humboldt detachment was closed in 1918 and was reopened on April 24, 1919 when one constable and one sergeant were stationed here.

In 1920 the North West Mounted Police officially became the Royal Canadian Mounted Police as the North West had become the provinces of Saskatchewan, Alberta and British Columbia.

The first recorded RCMP detachment quarters at Humboldt were taken over by the force on January 1, 1933. These quarters were situated on the second floor of the old Post Office building, now the museum on Main Street. In 1964 the detachment moved to a new building on the corner of 4th Avenue and Butler Street. At the present time the detachment is situated at 1004 11th Avenue.
