His name is Adam Thompson and he went missing Sunday night in only his pyjamas and socks.
Police are asking that if he is seen, that he not be approached as he will become extremely anxious. And, that anxious reaction could have a negative impact on an already existing heart condition.
If anyone has any information, they should contact the Halton Regional Police immediately at 905-878-5511.
Update Monday 6pm: Thankfully, there is a happy ending to this story. The young man was found alive and well late this afternoon some six kms from home. Police say he is in good condition. It has been a blessing that the temperature in Southern Ontario today has been in the mid 20s celsius.
