Brandon Pace, 19 of Hamrun, this morning pleaded not guilty to seriously injuring his cousin Ivan Farrugia and to relapsing.
Mr Farrugia was stabbed on the left hand side of his chest two days ago in Marsascala.
Informed sources said the two had argued over a girl who was going out with Mr Farrugia after having formerly been Mr Pace's girlfriend.
No request for bail was made
