A Madison man was arrested Thursday on tentative charges of possessing child pornography, police said.

Antonio O. Tecalero, 23, was arrested around 8 a.m. by Special Victims Unit detectives after a SWAT team executed a search warrant at his residence on the 6700 block of Schroeder Road, spokesman Howard Payne said.

The warrant was a result of a Madison Police Department investigation into computer crimes, Payne said, with assistance from the state Department of Criminal Investigations and the National Center for Missing and exploited Children.
