Melania Geymonat and Christine Hannigan were on the upper deck of a double-decker bus in Camden, north London, when three youths confronted them in the early hours of May 30 attempting to get the two to kiss.
CCTV of the incident shows the pair were surrounded and hit with coins before a fight broke out while they were travelling on the top deck of the N31 bus in north London leaving the couple with cuts and bruises.
Appearing at Wimbledon Magistrates’ Court on Thursday, the 16-year-old was given an eight-month youth referral order, increased from six months due to the homophobic nature of the attack.
He was also fined £100 and ordered to pay a £20 surcharge.
The 17-year-old youth previously denied joining in with the two other boys and harassing the women because he thought they were lesbians. However last month a judge rejected his claim and found he was motivated by hostility towards the two women for their sexual orientations.
He received a four-month youth rehabilitation order and supervision.
The third boy, aged 15, will be sentenced on December 23.
