Boy, 14, arrested on suspicion of drug offence at Fratton Station in PortsmouthÂ

The 14-year-old was on suspicion of being concerned in the supply of Class A Drugs at Fratton Station at around 2pm yesterday (November 12). 

The boy is from London. 

Tweeting about the arrest, Hampshire Constabulary mentioned county lines. 

So-called 'county lines' gangs are organised crime networks which exploit children to sell drugs. 

Often these children are made to travel across counties, and they use dedicated mobile phone '˜lines' to supply drugs. 

If you are suspicious that someone living on your street is a drug dealer or involved in drug trade, Hampshire Constabulary warn to look out for these signs. 

- A sudden increase in visitors to a house or flat and people only staying for a very short time.

- Short exchanges between small groups of people at or close to a flat or house.

- Residents leaving a flat or house on numerous occasions throughout the day and returning a short time later.

- People loitering in an area and using their mobile phones frequently.

- New-looking or hire cars parked outside a house or flat that wouldn't normally be there, and being driven by somebody that you wouldn't normally associate with driving that style of car.
