Two boys, aged 13 and 14, have been arrested in connection with two stabbings in Worthing in Sussex.
Police were called to South Farm Road at around 4pm on Tuesday after a 16-year-old was stabbed in the arm. He was taken to hospital for treatment.
Officers were then called to Goring-by-Sea railway station around an hour later after a stabbing in the car park, following a row.
A 16-year-old suffered multiple stab wounds.
He was taken to the Royal Sussex County Hospital in Brighton where he remains in a serious condition.
The two teenagers were arrested after a search by British Transport Police and a police helicopter.
We believe the two incidents are linked due to the similarities in the description of the suspects.
