Two incidents of racist abuse – one towards a taxi driver and the other against a woman in a car park – are being investigated by police.
A 28-year-old man has been arrested on suspicion of a racially aggravated public order offence.
This was after racist language was reportedly used towards a taxi driver in Kingsbury at 2.20am on Tuesday (May 28).
The man has been released on bail until June 25.
A separate incident took place in the Argos car park in Cambridge Close at around 3.30pm on Sunday (May 26).
A woman, accompanied by her sister, had just parked her car when a man parked next to her and is said to have used racist language towards her.
The man is white, of average build with short hair and was wearing sunglasses.
Acting chief inspector Emma Garside said: “Incidents of this nature will not be tolerated and I would like to reassure the community that incidents like this are rare.
“We have a diverse community in Aylesbury and work in conjunction with our partners to promote a safe and secure local area.
“We will do all we can to find those who commit crimes of this nature and our neighbourhood teams will continue to patrol the area, so if anyone has any concerns they can speak to one of our officers.
“I would like to ask the local community to remain vigilant and come forward to report incidents of this nature to the police immediately.”
