The New Democratic Party has sent what they're calling a "threatening" post by online activist group Anonymous to Halifax Regional Police.

On Monday, a group purporting to be Anonymous sent posted a statement to an online forum claiming members of Nova Scotia's New Democratic Party were using paid tweeters to influence the election. They likened the alleged actions to cyberwarfare against Nova Scotians.

At the heart of their allegations was an accusation that 250 Twitter accounts were created in government offices during the first weekend of the election campaign.

The New Democratic Party quickly spoke against the accusations, and the email offered no evidence.

The Anonymous post concluded by saying the NDP had 72 hours to stop its online behaviour or the group would release further details.

On Tuesday, the NDP released a statement saying they received a second statement from the group and decided to pass the matter on to Halifax Regional Police. Party officials said the timeline appears to be a threat.

"The NDP is very concerned not just about the possible threat in the emails, but by the fact that they contained anonymous and false allegations that were widely reported," David Wallbridge, the president of the Nova Scotia NDP, said in a statement.

"This gives a clear appearance that the email may have been a politically motivated dirty campaign trick."

The NDP is also calling on the Liberals to investigate to see if any members of that party were involved.

The Liberals had earlier said they had no evidence that any inappropriate behaviour was underway by the NDP online.
