A source said: “Trinity College authorities have been informed of the matter.

A source said: “The suspect is alleged to have attempted to poison his housemates using bleach in a coffee machine.
“His ‘plot’ was uncovered and he was confronted by the female student.
“It is claimed he has admitted what he did to the housemates - and allegedly claimed that he had done something similar in the past.”
The source added that the girl who found the bleach is now ‘too scared to return to college’ as the suspect has not yet been expelled.
A source said the suspect even admitted he had researched using bleach as a poison and knew the exact amounts to put in the espresso machine to damage his house mates.
When contacted, a spokeswoman for TCD refused to comment on the incident.
She said: “In the interest of student confidentiality, it is our policy not to comment on individual student cases.
