Detectives arrest a 51 year-old man in connection with the murder of a toddler in Lisburn in July

DETECTIVES have arrested a second suspect over the death a young boy two months ago.

A 27-year-old woman was dramatically arrested on Wednesday as the events of the death took a new twist.

Now on Thursday, police say a 51-year-old man has been arrested in connection with the child’s unlawful killing.

Detectives swooped on Wednesday and detained the woman in connection with the death of a three-year-old boy in Lisburn, County Antrim.

According to the PSNI, the boy was found dead on Thursday, July 4 at a house in Trinity Terrace.

The woman had not long moved into the house before the child died.

The results of a post mortem examination on the boy’s remains had until now been described as “inconclusive”.

However, detectives from the PSNI’s Major Investigation Team launched a murder inquiry on Wednesday following fresh information.

The woman was arrested on suspicion of the child’s murder and has been taken into custody for questioning.

The second suspect, a 51-year-old, is also in custody being questioned about the circumstances leading up to the child’s death.
