POLICE received 200 calls from the public after the pictures of two men sought in connection with the death of a Scottish schoolboy were screened on BBC's Crimewatch programme.
Isaac Purcell, 25, and Patrick Nolan, 19, are believed to have been in the car that killed 10-year-old Jack Anderson in Edinburgh.
Isaac Purcell's brother, Michael, 19, was arrested in Ellesmere Port and later charged with culpable homicide following the incident on Thursday, October 5.
He is also facing three charges of attempted theft, one of theft and another of attempting to pervert the course of justice and is remanded in custody.
Police say there is a possibility that the two other suspects might also be in the Ellesmere Port area.
They are both well known within the Gypsy traveller community and detectives are making a specific appeal for their help.
A Lothian and Borders Police spokesman said: 'We have been delighted with the response from the public.
'We have received around 200 calls, which we will now sift through and establish what lines of enquiry we have.'
Jack's parent's Michael and Yvonne also made an appeal for information.
The youngster was walking home from Carricknowe Primary School when he died.
The vehicle involved failed to stop and was found abandoned a short time later.
A Scottish daily newspaper is offering a £10,000 reward to anyone with information that leads to the arrest and conviction of those responsible for Jack's death.
