Questions have been raised over the murder of Daniel Pelka, after his mother and stepfather were jailed for 30 years today.
A couple have been jailed for a minimum of 30 years for murdering four-year-old Daniel Pelka, in March 2012.
A "callous and wretched" mother and her partner are facing life sentences for murdering systematically abused four-year-old boy.
Two people have been arrested on suspicion of murder after a two year-old boy was admitted to University Hospital Coventry onMonday with serious head injuries. The toddler died on Tuesday at Birmingham Children's Hospital.
A 21-year-old man and a 25-year-old woman were arrested.
The initial post-mortem proved inconclusive over the cause of death.
A children's services boss who was criticised for failings by his former council over murdered schoolboy Daniel Pelka has stepped down from his new child protection post.
Tower Hamlets Council said Colin Green had withdrawn as chairman of the Local Safeguarding Children Board "with immediate effect".
He had taken the role after retiring as Coventry City Council's director of children's services last month following revelations about failings by his department over the boy's death.
The former director of children's services at Coventry City Council, who missed opportunities to intervene in the Daniel Pelka case, has been appointed to a new child protection role - in a move that has been heavily criticised.
Colin Green retired from the council at the end of last month but is now set to become the independent chairman of Tower Hamlets Safeguarding Children Board in London.
A serious case review into the death of Pelka, four, who was beaten to death by his mother and stepfather, found that opportunities were missed by the city's children's services team.
The review also claimed health professionals, school staff, police and other child protection agencies misses signs for an intervention.
Geoffrey Robinson, Labour MP for the area of Coventry where Daniel and his family lived, said he was "stunned" at the news of Mr Green's appointment, which he claimed was "an affront to public opinion".
A teenage girl has been arrested on suspicion of assaulting an 80-year-old man in a "nasty" city centre attack, that left him with a bloodied nose and black eye.
Police said the 19-year-old was arrested yesterday afternoon in Gloucester and would now be questioned about the attack in Coventry on August 10 when the elderly victim was punched in the face and shoved to the ground.
A passer-by recorded the attack on their mobile phone and the footage has been circulated widely on social media websites.
Coventry Police chief superintendent Andy Nicholson, said: "This was a despicable, violent attack on an elderly man in broad daylight. The victim is an 80-year-old man - he was left with a bloodied nose and a black eye.
"A video showing the assault spread rapidly on social media and quite rightly the offender's actions are being condemned by everyone who's viewed it."
Anyone with information about the attack near Sainsbury's in Coventry's Trinity Street should contact West Midlands Police on the 101 number or Crimestoppers anonymously on 0800 555111.
Questions are being raised over the death of Daniel Pelka and how he could have been allowed to be subjected to such "despicable torment", the chief executive of the NSPCC said today.
Peter Wanless added:
There are many brilliant professionals and citizens who are alert to the signs of abuse, whose timely actions to prevent harm never make the headlines.
But, when adults are hell bent on destroying a child's life and doing all they can to deceive those around them, the criticality of questioning a child's behaviour and speaking out about it is more important than ever.
Amy Weir, the chair of the Coventry Safeguarding Children Board has told ITV News that it was "critical to get to the bottom" of the Daniel Pelka case, as it has had a "devastating affect on lots of people around him".
The father of Daniel Pelka has said that the life sentences handed out to Magdelena Luczak and Mariusz Krezolek were "severe enough", but he only "wishes the same thing would happen to them, what happened to my son".
Following the sentencing, Eryk Pelka told ITV News that he was "not relieved a single bit". He added: "When we were a couple, Magda was a good mother. I think that, he had a bad influence on her".
Children's Commissioner for England Dr Maggie Atkinson has told ITV News that the murder of four-year-old Daniel Pelka is a "warning for us to keep vigilant".
Dr Atkinson added that information emerging from a review reveals that "signs were seen" over the abuse, "but was not followed through".
Speaking to ITV News, Amy Weir - Chair of the Coventry Safeguarding Children Board - said it was very important to have an independent review to "stop tragedies like this happening again in the future."
