A man has been arrested on suspicion of attempted murder after a 10-year-old boy was stabbed in front of his mother in a street in Leicester.
Police said the child was in Belper Street in the Belgrave area of the city on Saturday when a man stabbed him and ran from the scene.
The boy was treated in hospital for non-life-threatening injuries and later discharged.
A 32-year-old man remains in custody after being arrested on suspicion of attempted murder.
It comes after police released a CCTV image of a man they wanted to identify in connection with the case.
Detectives are linking the attack to two others in the area during the past week.
A woman in her 30s suffered a cut to the back of her head in Doncaster Road at about 7.15pm on 14 January.
Then two days later a man in his 70s was found with injuries to his head and hands in Dean Street.
Both victims were also taken to hospital for treatment and later discharged.
Detective Inspector Tim Lindley, of Leicestershire Police, said: “Following a public appeal issued to trace a man captured on CCTV, a 32-year-old man has been arrested.
“While I would like to thank everyone who has shared our appeal and has already made contact with police, I am still appealing to anyone with any information to come forward.
“If you witnessed any of the incidents or have CCTV or dashcam footage from the area you could have vital information to assist us with our continued enquiries.
“Please speak to police if you can help.”
Anyone with information can call police on 101, quoting incident 145 of 19 January.
