Manchester City defender Ben Thatcher is to face a second police inquiry over an incident during a reserve team game earlier this year.
Thatcher already faces questions from Greater Manchester Police after the force received complaints from the public over his horror tackle on Portsmouth's Pedro Mendes last month.
Ralph Welch, a 19-year-old Blackburn Rovers player, has complained that he was elbowed in the face by Thatcher during a match at Christie Park, Morecambe, in February.
A spokesman for Lancashire Police said: 'We have had correspondence from Merseyside Police and we are investigating the matter.'
Thatcher was banned for six games and fined £120,000 by his club after video footage showed him smash Mendes in the face with his elbow during City's home match against Portsmouth on 23 August.
He has apologised to the player who was left unconscious by the collision.
Thatcher faces an FA disciplinary hearing on 12 September.
