Detectives investigating the murder of Logan Mwangi, five, have seized doorbell camera footage from the street in the hope it will provide answers to his death.

A woman, 30, a man, 39, and a 13-year-old boy, who cannot be named for legal reasons, have been arrested on a suspicion of murder after Logan's death.

Logan was reported missing at around 5.45am on Saturday after neighbours heard his mum desperately shouting "the back door was open".

Meanwhile, police divers spent a third day searching the waters of the Ogmore River in Sarn, south Wales.

Neighbours said officers were seen removing items of clothing from the riverbank.

One man claimed: "One of our neighbours said the mum had a camera fitted on her doorbell.

"The police took the doorbell because it recorded what had happened."

A mum said Logan had been self-isolating at the family home after testing positive for Covid.

Another mum, who lives near Logan's home, said: "I know that one of the neighbour's saw a man near to the river at quarter to five in the morning.

"That was before the police turned up.

"The police were pulling clothes from the riverbank. I don't know if they were Logan's or not.

"He was such a sweet and quiet little kid. My little one used to ask to go and knock for him to play but he never came out really.

"Logan's mother used to say hi if you passed her but she kept herself to herself.

"This is a quiet street so we never expect to see anything like this."

A couple, who live on the street, said Logan and his mum had knocked on their door just a week earlier after finding a snake in their garden.

The woman said: "I can't believe he has gone. He was so innocent and lovely.

"They knocked on our door not long before he died because they had found a snake.

"He was a sweet little boy."

One woman said: "I heard someone running past and screaming at 6am. I didn't know what had happened."

A mum said Logan was her daughter’s best friend.

She said: “He was smart, intelligent, happy, polite. He had a smile that lit up the world. He didn’t deserve this.”

A spokesperson for South Wales police said on Sunday: "We can confirm that following reports of concerns for a missing five-year-old boy in Sarn, Bridgend, and the subsequent finding of the body in the Ogmore River near Pandy Park, three people have been arrested.

"A 39-year-old man, 30-year-old woman and 13-year-old boy, all from the Bridgend area, have been arrested on suspicion of murder. We are not looking for anyone else in relation to this incident."

Today they identified the boy as Logan Mwangi, also known as Logan Williamson, and confirmed the suspects remained in custody.
