At least 48 people were injured when a bus carrying wedding guests skidded off the main road in Bhaktapur on Thursday.

The ill-fated bus (Ba 4 Kha 1905), en route to Koteshwor from Nagarkot, plunged into an adjacent road at Jitpur along the Kamalbinayak-Bhatkyapati-Nagarkot road section in Nagarkot Municipality-7.

DSP Mitra Bandhu Sharma said 21 of the injured were receiving treatment at Bhaktapur Hospital and as many were admitted to Madhyapur-Thimi Hospital. Two other injured have been taken to Jorpati-based Orthopaedic Hospital, said DSP Sharma.

Condition of four injured is said to be critical.

Police said overload could have caused the accident.

The 25-seater bus was crammed with around 60 people when the accident occurred.
