TORONTO – Ontario Provincial Police made an arrest Friday in the hit-and-run case earlier this week that left a seven-year-old Ajax boy dead.

Jose Olmedo Renteria, 30, from Toronto, faces dangerous driving, criminal negligence causing death and failing to remain at the scene of an accident charges in the incident that killed Jacoub Favila the OPP said in a news release.

Bloomy Favila, Jacoub's mother, said she is relieved police have arrested someone.

"I have no words for him," she said in a telephone interview. "He just needs to serve what penalty he deserves. It cannot bring back the life of my son. For somebody to do what happened to our son - it speaks volumes of what kind of individual he is."

She added her surviving son Joshua feels "he's not a twin anymore."

"He's sad," Bloomy said. "I said he'll still be a twin to Jacoub. I know it's a long process for him, that's why we bring friends and kids over to talk to him."

Renteria was stopped and arrested Friday evening without incident on the eastbound lanes of Hwy. 401, near Cobourg, the OPP said.

Police allege Renteria was behind the wheel of a silver Hummer H2, which smashed into the back of a Honda Odyssey on the 401, near Dixie Rd on Tuesday.

Jacoub was transported to Trillium Hospital where he died.

Two adults and five other children -- including Favila's twin brother Joshua -- who were in the minivan during the crash were unhurt.
