Regional police dive teams are heading back into the Housatonic River in New Milford today as they search for two New York men swept away from where they were swimming on Wednesday.  The 21 and 24 year old Bronx men were picnicking with a group adjacent to the Bulls Bridge Power Plant when one struggled in the water, the other jumped in to help.  The search was called off yesterday due to heavy rain and possibility of lightning.  The Brookfield Police Dive Team will pick up the search today.  Police say the identities of both victims are not being released until search, rescue or recovery activities are completed.
