Letter-bomb suspect accused of tainting water

This court sketch depicts Adel Arnaout, suspected of sending out letter bombs in Toronto. Arnaout made his first appearance in court on Aug. 31, 2007.

A man accused of being involved in a letter-bomb scheme has now been charged with eight additional counts of attempted murder in a separate poisoning investigation.

The suspect is the same man police arrested in August for mailing three letter bombs to three homes this past summer. Now, he's accused of sending tainted-water bottles to two Toronto-area modelling agencies in 2004.

Investigators allege the suspect sent the agencies bottles of water tainted with a chemical that he injected into the drink himself.

Upon close inspection, people at the office realized the bottles had been tampered with and called police.

The suspect was charged in August with three counts of attempted murder and three counts of intending to cause an explosion for allegedly mailing explosives to two homes in Toronto and one home in Guelph.

Police said they found three improvised explosive devices in the suspect's car at the time of his arrest.

After making the arrest, police continued their investigation and were able to link the two incidences.

"The accused and the victims, there is a relation between them," Const. Wendy Drummond told CTV News. "It wasn't totally random.

Adel Arnaout, 37, is scheduled to appear in court on November 16 to face charges of attempted murder. The eight counts are in addition to the previous charges.
