Police says reports a young boy was followed by a man in a white van cannot be validated - but have appealed for anyone with information to contact them.
Officers were told the boy was on Bolton Road West in Ramsbottom at around 3.40pm on Tuesday when he was followed by the driver.
But "following a detailed police investigation, officers were able to negate this particular report", GMP has said.
