ANTIOCH -- Police say they're sending extra patrols during the "release hour" after a suspicious man tried to convince a 10-year-old boy to get in his car Thursday afternoon near Sutter Elementary School.

The fifth-grader was walking through a parking lot to meet his grandfather when a man in a '70s-era light blue car tried to talking him into getting in, according to Antioch police Sgt. Trevor Schnitzius. The man told the boy his aunt had sent him to pick the child up.

The man "made no effort to grab the child," Schnitzius said.

The boy told the man "I don't know you" and walked away, according to a message sent by Sutter Principal Paula McEvoy.

McEvoy said Friday that teachers at the school were re-emphasizing lessons in "stranger danger" to students. Children should be taught not to talk to strangers, to walk away if someone says a family member sent them and the child doesn't know who they are, and to be aware of surroundings.

The man was last seen near Chichibu Park, which is adjacent to the school on G Street. There have been no other recent reports of anyone trying to coax a child into their car, Schnitzius said.
