About 3.10pm on February 10  two local men and a local youth aged 21, 19 and 14 were seen riding their bikes along Ravenshaw St.

Near the intersection of Elliot and Ravenshaw streets the 19-year-old started riding his bike repeatedly back and forth across the road.

There was heavy traffic in the area at the time with school just breaking up.

None of the three were wearing helmets.

All three were issued with fines for riding without a helmet. The 19-year-old was fined for riding in a negligent manner.

Less than 10 minutes later, the 19-year-old was seen riding his bike near the intersection of Ravenshaw and Hay streets.

The teenager was travelling along a footpath and as he jumped off a gutter he performed a skid, almost hitting two high school girls 

walking nearby. The teen was not wearing a helmet.

He was issued with a fine for not wearing a helmet, riding on a footpath and riding recklessly.

About 10am the following day a 19-year-old was stopped by police while riding his bike on Church St.

The teen was riding on the footpath without a helmet.

A 14-year-old riding a short way behind on a skateboard was also fined for not wearing a helmet and riding on a footpath.

People caught riding on a footpath in the CBD can be issued a $110 on the spot fine.
