A 20-year-old admitted to stabbing a stranger in broad daylight during a short break from seeking career advice.
Andre MacCarthy, of Francis Road, Harrow, admitted at Harrow Crown Court on Tuesday one charge of wounding with intent in connection with the attack on September 3 last year in the middle of St Ann's Road, Harrow.
MacCarthy had left career advice centre Connexions in nearby College Road to go to a Londis supermarket where he purchased the offending weapon before planning to return to Connexions.
The defendant, however, became involved in an altercation with a 16-year-old, who he did not know, in which he smashed the bottle to use as a weapon.
Simon Wild, prosecuting, told the court closed circuit television footage examined by police officers showed MacCarthy making three swings with a bottle before a bus arrived and blocked the view.
The victim, who is now 17 and cannot be named for legal reasons, sustained an injury to the left arm and a chip to the bone.
Police officers brought Harrow town centre to a standstill at 2.45pm when they were called so forensic work could be carried out in the area around the statue of Skipping Katie.
MacCarthy is due to return to be sentenced at Harrow Crown Court on February 18, and has been bailed in the meantime and ordered to obey a curfew of 7pm until 6am a curfew and will be monitored by electronic tag.
