A sibling of a four-year-old boy allegedly murdered by his mother and stepfather told a court they saw him being held underwater in a bath at the family home.

Daniel Pelka died from a head injury in March 2012 in Coventry after an alleged campaign of "incomprehensible" cruelty.

His mother Magdelena Luczak, 27, and her partner, Mariusz Krezolek, 33, both from Poland, deny murder and causing or allowing Daniel's death.

Ben Ando reports from Birmingham Crown Court.
