Approach controller at msp observes traffic from another facility in his sector on a conflicting course with his traffic. Although an evasive vector was issued to avoid the intruding aircraft, the incident resulted in a loss of separation between the 2 aircraft.

Narrative:
I observed an aircraft in my airspace, without a pointout on a conflicting course with my traffic. When I found out the aircraft was not being controled by a controller in my facility I issued traffic and issued an evasive vector. I observed the second aircraft at 13000 ft, 2 mi apart and decreasing.
