Death threats made online to Liverpool striker Luis Suarez are reportedly being monitored by police officials, who have warned against aggressive conduct on social networking sites.

Suarez has been consistently linked with a move to Arsenal during the last two weeks, leading to angry tweets from a number of Reds fans.

One account with the Twitter handle @JoshuaWhateley posted a message directed to the Uruguayan striker which read: "If by any chance Liverpool do accept a bid, and you move, I will find you and I will kill you."

Another fan is quoted by the Daily Star as posting: "Can Arsenal just f*** off. If Luis Suarez leaves I'll hunt him down and kill him."

A police source issued a statement to the Daily Star on the messages earlier today, declaring: "People should be aware they can be held accountable to the law for anything they write on social networking sites."

Liverpool have rejected two bids from Arsenal for Suarez in the past seven days, with managing director Ian Ayre adamant that the forward is not for sale.
