Detectives investigating the death of an 81-year-old Birmingham widow found gagged and suffocated at her home have arrested a man on suspicion of murder.

West Midlands Police said the man, in his 30s, was detained in connection with frail Mohinder Kaur’s death.

Mrs Kaur’s body was discovered at her flat in Kings Heath, by one of her sons on August 25.

The grandmother had been gagged around the mouth and robbed of more than #1,000 worth of gold jewellery, including rings, bangles and chains.

A police spokesman said on Thursday: "Officers from the Major Investigation Unit have this morning arrested a local man, in his 30s, on suspicion of murder."

Described by her family as a happy and sociable woman, Mrs Kaur, known to her family as Shanti, was found gagged at her flat on Nutgrove Close.

Her door had not been forced open, but had been left unlocked, police said. A post-mortem examination showed Mrs Kaur, who had five children and a number of grandchildren, died from suffocation.

The pensioner, who was hard of hearing and spoke little English, was last seen alive in nearby Albert Road on the evening of August 25.
