Detectives have refused pleas to conduct a criminal investigation into a regional journalist’s death.

Greater Manchester Police says it will not launch a probe into the case of former Manchester Evening News journalist Teresa McMahon, who died after being found hanged at her flat in 2021.

Earlier this year, Teresa’s niece Lorna McMahon called for a criminal investigation into her death after claiming she would not have been capable of killing herself.

A report earlier this year revealed that GMP officers delayed seeing Teresa, pictured, for nine days when she made a domestic abuse allegation and also failed to inform her of her former partner’s violent history when she requested it under Clare’s Law before her death.

According to the MEN, a detective chief inspector from GMP’s major incident team has now carried out a review of the original investigation and has concluded a criminal investigation is not warranted.

The officer also found the original investigation was not flawed, while a further report by GMP has found that the force was not at fault in relation to allegations made by Ms McMahon.

A letter from GMP to her, which states “a sufficiently thorough, reasonable and proportionate investigation” was carried out, said: “There is no requirement to refer this matter to the Crown Prosecution Service.

“I do not find any cases of misconduct against the officers subject of this complaint or other individual officers or members of police staff. There is no evidence the officers’ performance has been unsatisfactory.”

Referring to the failure of GMP to disclose information to Teresa under Clare’s Law, the letter added: “I have however identified an area for organisational learning stemming from this complaint.

“It is apparent that the myth around an applicant not being eligible for a disclosure if they are no longer in a relationship may still persist amongst uniformed frontline officers.

“This will therefore be submitted to the organisational learning board for them to assess the best way forward in rectifying this so learning can take place on an organisational level.”

Mother-of-one Teresa, 43, worked for the MEN on a freelance basis between 2014 and 2016 and has also been a producer for Granada TV.

A spokesperson for GMP told the MEN: “Our thoughts remain with Ms McMahon’s family at what continues to be a difficult time and officers remain in contact with them.

“The force will not be commenting on this case any further until the conclusion of coronial proceedings.”
