The father of a suspect involved in a police investigation is accused of threatening a Michigan State Police detective trooper on LinkedIn.

Police were alerted Tuesday about the threatening message sent by Joseph Michael Keith, 55, to a member of the MSP Computer Crimes Unit on the social networking site. 

Keith was interviewed at his St. Clair Shores home, where police determined there was probable cause to arrest him. He was taken into custody and arraigned Wednesday on a charge of malicious use of a telecommunications service.
