A senator from Maine is calling on U-S Secretary of State Hillary Clinton to investigate the lobster dispute unfolding in New Brunswick.    
Fishermen in the province have been protesting the import of low-priced lobsters from Maine, saying that prices for their own catch are being driven down as a result.    
The flare-up came to a head last week, when fishermen held demonstrations in Cap-Pele and Shediac, and trucks were prevented from delivering Maine lobsters to three processors.    
In a letter to Clinton, U-S Senator Olympia Snowe said any acts of intimidation, violence or coercion cannot be tolerated.
