Montreal police have released a sketch of a man they are calling "an important witness" to what happened earlier this week in a parking garage in Cote Saint Luc.
A 74-year old woman was robbed and beaten with a baseball bat. She remains in hospital in critical condition.
Investigators will be manning a command post outside the building on Cavendish Boulevard from ten o'clock this morning to two o'clock this afternoon, hoping to speak to anyone with information about the attack.
