A teenager tearfully told a Supreme Court jury how blood gushed from her friend's face after an alleged attack.

Jewels Fox said she didn't see Garrina Cann or Trimiea Roland hit Brittany Symonds on the head with a rock and a stick, but later saw her friend covered in blood.

The 18-year-old told the court: "She had all this blood over her face and I still couldn't recognise it was her because [of] a bunch of blood and blood squirting from her head.

"I was trying to help her because I thought that something was wrong but I didn't want to tell her because the way the blood was squirting out, it looked serious. I was trying to push my finger down on the spot. It was like it wouldn't stop bleeding."

Miss Fox testified yesterday in the case of Cann, 21, and Roland, 22, who deny wounding with intent to do grievous bodily harm.

Miss Symonds needed ten stitches and four staples in her head as a result of the alleged attack.

She also needed two stitches in her upper back and three in her left thumb after the February 2 incident.

The court heard the 17-year-old was attacked by Cann and Roland after refusing to hand over her cell phone.

Miss Fox said the night started at a party at Tyneisha O'Connor's home on Sofar Lane, St. David's.

She said she arrived with her sister Keva Outerbridge but only stayed for 30 minutes because she felt unwell.

The witness told the court she caught the minibus back home to Ferry Reach, got a shower and came back to St. David's later that night.

Miss Fox said she got off the minibus near the bus stop below the St. David's Lighthouse and met her sister and Miss Symonds.

A few minutes later her sister "sprinted" past her.

Miss Fox said she then saw Roland, Cann and two unknown men walking towards her.

She said Cann and Roland accused her sister of stealing an iPod or iPod box Cann said she wanted to fight her.

Miss Fox said she told Cann where her sister ran and then the group left the area.

She said she stayed at the bus stop for a few minutes then received a call from Miss Symonds but couldn't make out what she was saying.

"I heard Garrina yelling in the background. She [Miss Symonds] was trying to tell me where she was. She was telling me to come down the one way but she wasn't telling me where," she said.

Miss Fox said the phone call got disconnected so she decided to find her friend.

"I stopped someone who was riding to the bus stop. I didn't know the male. He rode down slowly on Mount Road one way. I heard commotion before you get to the road to Southside. It wasn't yelling, it was stern talking.

"I saw a big person by a ledge with a person pushed to the wall ledge. I could see the big person's back. The big person was reached out over somebody. When the big person turned around, I recognised it was Garrina."

She said Cann then walked over to her with a 20-inch wooden stick in her hand, grabbed her by the wrist and said: "You don't want to get in this."

She described Cann as being very angry and giddy, and said she looked drunk.

Miss Fox said moments later, Roland ran past her with a bottle in her hand and said, "Rina, I got her. Rina, I got her."

Miss Fox said after the incident, she ran to a house and got the residents to call the ambulance for Miss Symonds.

Cann's lawyer Marc Daniels suggested Miss Fox was lying on "bits and pieces" of her evidence but the witness disagreed.

He also suggested his client never grabbed the witness nor had a stick in her hand, but Miss Fox again disagreed.

The trial continues.
