A woman from Bitterne has noted her concern as "problem" motorbikes have been riding around a popular dog-walking field this week.

The woman, who asked to stay anonymous, told the Echo that teenagers on bikes have torn around Riverside Park "every day" that she has been at the fields this week.

She explained that she has been reporting the teens' anti-social behaviour to the police, who confirmed that they were "working to tackle the issue".

The woman said: "The first day I didn’t report it because they were in and gone quickly, but now they are loitering half an hour and longer.

"They stop for a bit, hang around, then start again around the cricket pavilion and keep going really loudly."

She said that she has had to keep her dog on a leash, and that if bikes came near her pet, it would probably "lunge" out at them in fear.

"It's a problem for dogs and children. A dog is going to get hit with the way they’re racing around," she said.

"It’s not so busy in here now because people are probably avoiding it. My dog would start lunging at the bikes on the long line. Somebody’s going to get injured if it keeps going on. It’s daily, every time I’ve come down 4.30ish, they’re already here."

The woman explained that it feels like hard to report the bikers, as contacting 101 takes "too long" to get a response, and it is "not an emergency enough" to call 999.

"On 101, police did say they were going to get people to investigate, but by the time I got an email I think they were gone," the woman said.

But a spokesperson from Hampshire police urged any members of the public to continue to report bikers in the park.

The spokesperson said: "We can confirm we have received reports of ongoing anti-social behaviour relating to teenagers riding motorbikes in Riverside Park.

The Bitterne Neighbourhood Policing Team are aware of these incidents and will be working to tackle the issue via targeted and increased patrols.

We ask that the public continue to report this to us, and include any descriptions of bikes and riders to enable us to identify who is involved and take action. Any photo or video evidence can also be submitted to help us tackle the issue.

"The more we know about it, the more we can do to target it."
