A yob knocked an innocent cyclist off her bike during a month-long crime spree in Blantyre.
Dylan McSkimming also took part in a supermarket robbery and seriously assaulted a man.
McSkimming 18, appeared from custody via videolink at Hamilton Sheriff Court.
He admitted assaulting Sharon Dunn by throwing a plastic bottle which hit her on the face, knocking her off her bicycle.
The unprovoked attack happened in Glasgow Road on February 12.
Jennifer McLaren, prosecuting, said the victim flagged down a passing police car. She was “extremely shaken”, but suffered only a minor injury.
McSkimming also admitted that he and unknown accomplices assaulted Darren Crooks to his severe injury and permanent disfigurement on February 29.
Police were called to a flat in Stewart Avenue and found Mr Crooks lying unconscious on the floor.
He had suffered a broken nose as well as cuts to his face and head. He was treated at Hairmyres Hospital and needed 15 stitches.
Ms McLaren told the court there was blood in a bedroom, the hallway and the living room.
Mr Crooks at first refused to say who had attacked him, but police found that McSkimming had posted a video on Facebook.
McSkimming had filmed Mr Crooks backing into a corner. Mr Crooks punched an unknown male and then McSkimming jumped up from the couch and became involved.
The fiscal added: “Mr Crooks later told the police McSkimming had ‘given him a doing”, but said he couldn’t identify the other attackers.”
McSkimming and a 17-year-old Blantyre youth also admitted robbing staff at knifepoint at Asda in Blantyre on February 10.
They were confronted by the nightshift manager and a security guard at 1.30am.
The 17-year-old produced a knife and made threats. McSkimming fled with two bottles of Morgan’s Spice rum.
McSkimming further admitted stealing alcohol and electrical equipment on three separate occasions at the same Blantyre Asda in February, and lager from Scotmid in Coatshill Avenue, Blantyre, also in February.
Referring to the robbery in Asda, defence agent Andy Iles said McSkimming had no idea his co-accused was armed.
On the assault that he filmed, Mr Iles said his client got involved initially to help his friend who was under attack from Mr Crooks.
Sheriff Douglas Brown deferred sentence on both accused until September 11 for criminal justice social work and electronic tagging reports.
McSkimming was remanded in custody while his co-accused had bail continued.
