Family in stationary car moped robbery per the BBC

Another day, another armed robbery in London. However this one has a detail about the perpetrators that is not in the usual BBC reports, can you spot it? 

'A family of four were robbed by two masked men on a moped as they sat in a stationary car in Croydon, south London.

One of the suspects threatened the family with a large knife on Keats Way, Coulsdon, at about 17:45 BST on Friday.

Police say the pair made off with a "small quantity of jewellery".

A 30-year-old woman suffered a cut to the hand during the robbery, as one of the suspects attempted to steal her bracelet.

It is believed that the other man also had a knife.

Detectives described the suspects as two white males, aged in their late teens or early 20s.'

'White males'? Race seems to be rarely reported by the BBC if the suspects are not white, I wonder why.
