Two boys thought to be aged between 13 and 14 have been arrested after an elderly man was attacked in the street.
It happened in Newsome, Yorkshire, shortly after 8am, with the victim reportedly suffering a head injury.
Two children have been arrested, with both believed to be in Year 9.
A section of the street was cordoned off by officers, with a small pool of blood seen in the street.
West Yorkshire Police (WYP) has confirmed two males have been arrested in connection with the incident but has not confirmed the ages.
However YorkshireLive understands the two suspects were in Year 9.
One eyewitness said the victim was left with a “big crack in the back of his head” after being attacked by two young males.
The elderly man was helped by a nearby resident before being rushed to hospital where it is thought he is being treated for non-serious injuries.
A spokesperson for WYP said: “The call came in at 8.11am. A male has been taken to hospital with a head injury – not thought to be serious at this time.
“Two males have been arrested and enquiries are continuing.”
Kirklees councillor, Andrew Cooper (Greens, Newsome), said: “Obviously it’s appalling when something like this happens.
“We have to get to the bottom of what happened here and make sure it is dealt with properly.
“The people involved need to recognise that this is unacceptable behaviour in a civilised society.
“Occurrences like this are very rare which makes it even more shocking when they do happen.”
