LAVAL - Bad weather has forced a halt in plans to scour a river near Montreal for a missing autistic toddler.

A Laval police spokeswoman says searchers had hoped to check a small bay near the shoreline home where three-year-old Adam Benhamama was last seen.

But a lightning storm and poor weather today forced officials to cancel their plans to resume the search.

The boy disappeared April 3 while playing with his seven-year-old sister.

His father had momentarily gone inside a friend's house when his daughter alerted him the boy had vanished.

Authorities say the child has a hearing impairment and can make sounds but is non-verbal.

Laval police Const. Nathalie Lorrain says the search is coming an end, although no firm decision has been made yet to stop looking for the boy.

She says warm weather is melting ice on the Mille-Iles River, but Lorrain expects operations to wrap up once a search of the small bay is completed.
