APPEALING FOR FOOTAGE. PILLION LEG RUN OVER BY LORRY!!

I am helping this rider to appeal for witness with regards to this accident.

They were travelling along SLE towards BKE on 4 May 2018 around 1915hrs.

The pillion‘s leg was run over by the lorry and is hospitalised for many days. The rider suffered some bruises on the face and limbs. They were too shocked to note down any number plate of either vehicle. They only can tell the taxi involved is red in colour. Please help to share. Thanks a million. 感恩。
