Montreal police are using divers to search the Riviere des Prairies today to search for Ariel Jeffrey Kouakou, a week after the 10-year-old boy went missing.
This is the first time divers have entered the river since the boy left home last Monday afternoon and disappeared while walking to a friend's house.
Officers have also gone door to door, searched backyards and used horses and all-terrain vehicles to search the Ahuntsic-Cartierville neighbourhood where the boy was last seen.
Police say they have received nearly 600 tips from the public since the boy disappeared.
The reward in the case meantime has reached $75,000 after a $50,000 donation from businessman Bruno Rodi today.
Local boxing champ Adonis Stevenson announced yesterday he would donate $15,000 to the boy's family, who had already announced a $10,000 reward to anyone who helps find their son.
Late last week, a GoFundMe page was set up by staff members at Berges-de-Lachine elementary school in Lachine, where Ariel's father works as a teacher. It has so far raised more than $25,000.
The boy's father has told reporters he's convinced his son was abducted.
