A northeastern B.C. newspaper has received another letter claiming to be from a bomber who has targeted EnCana facilities, with an ominous warning that "a long hot summer is coming."

Dan Przybylski, publisher of the Dawson Creek Daily News, said the latest letter is vastly different from two previous letters and he has turned it over to the RCMP who will try to determine if it is another hoax.

Przybylski said the most recent letter was typed, rather than being handwritten like the previous two letters received by the newspaper.

RCMP Sgt. Rob Vermeulen said the newspaper has already received one letter that was determined to be a hoax by police.

"We're not going to speculate at this point whether it's authentic or not, but investigators are working to determine that," said Vermeulen.

The most recent letter said the "time-out is over" — perhaps referring to a previous letter which called for a "break" in the activity — and warns "the long and 'hot' summer is coming," according to reports.

The letter states there will be "actions against installations" owned by oil and gas giant EnCana and taunts the police for the failure of their previous investigations.

Since October 2008 there have been six bombings of oil and gas facilities in northeastern B.C., and despite offers of a $1 million reward, police have laid no charges in the cases.

A recent search of Alberta resident Wiebo Ludwig's home failed to lead to any charges as well.

Many residents in northeastern B.C. and Alberta have expressed concern that the toxic sour gas wells and pipeline operated by EnCana pose a health risk to residents and livestock.
