Sarnia police have identified the person who called 911 from a cellphone nearly 400 times since Christmas day.

The caller is a 10-year-old hearing impaired and developmentally delayed student that cannot speak and attends a local public school. 

After hearing the story, an educational assistant at the school informed a teacher there.

The teacher was aware the student enjoyed playing with technical gadgets and lived in the area that the calls were coming from - police narrowed the location to a one-kilometre radius.

The teacher used the phone to place a call to Sarnia police on Friday.

The parent of the student had pulled the SIM card from the phone, thinking it would have no service capabilities and gave it to the child knowing the child was interested in electronic gadgets.

The child was not aware that 911 was being contacted each time.

There will be no charges laid.
