A two-year-old and a five-year-old boy have been found dead at a property in east London.

Scotland Yard said an investigation has been launched into the deaths, with a man and woman both known to the children arrested nearby.

Emergency crews rushed to the property in Cornwallis Road, Dagenham, at around 2pm on Friday, December 16.

Inside, they found the bodies of the two children, who were both declared dead at the scene.

Their family has been informed and will be supported by specialist officers.

The Metropolitan Police said in a statement: ‘A woman was arrested a short time later in connection with the incident. She was arrested after police were called to a disturbance at a residential address near to the scene.

‘A man was also arrested near to the scene in connection with the incident.

‘Both the man and woman remain in police custody.’

The statement added: ‘The arrested woman and man were known to both children.’

Detective Inspector Sean Treweek said: ‘This is clearly an extremely distressing incident with many unanswered questions, however at this very early stage, nobody else is sought in connection with the deaths.

‘I want to thank local people for the assistance they have given officers as they begin work along with partner agencies to establish the full circumstances of these two tragic deaths.

‘They will see additional officers in the area, and anyone with information or concerns should speak with those officers.’

Cordons remain in place at the location and enquiries continue.

Any witnesses or anyone with information that may assist the police investigation are asked to call 101, ref CAD 3408/16dec.
