One person is in custody following an apartment fire in St. Paul Tuesday night that appears to be intentionally set. 

The St. Paul Police Department said at about 6:15 p.m., officers responded to the 1600 block of Marion Street on a report of a man with a knife outside an apartment building. The 911 caller said the man approached him with the knife and followed him inside the building. He then saw the suspect pour a substance and then a short time later, his door was on fire and fire was coming into his apartment. 

The suspect then fled the scene. 

When officers arrived at the three-story apartment building, they saw smoke coming from the second floor of the building as well as visible flames on the back stairwell.
