Two men from Cardiff remain in a critical condition in hospital after taking what police believe is a legal high.

Cardiff and Vale University Health Board is to carry out consultations with management and unions over staff reorganisation which could lead to redundancies.
The service change plans potentially affect around 385 employees says the health board.
“Many of these plans involve redesigning a number of services to deliver the same, or better, care in a different way, and in a more cost effective way. This includes reshaping the UHB’s workforce, in line with what has been proposed," says the board's Chief Executive, Adam Cairns.
The health board employs 14,500 staff and says redundancies will be a "last resort" and staff who need to change roles will be offered training to assume new responsibilities.

A suspension order against the midwife heavily criticised for her role at the birth of baby Noah Tyler, who died after suffering brain damage when he was born, will continue. Julie Richards' suspension will be reviewed in three months, a malpractice hearing ruled this morning.
Yesterday, Cardiff coroner Mary Hassell said Ms Richards blamed "gross failure" to provide adequate care for Noah's difficult birth, and subsequent death when he was just 10 months old. Earlier in the inquest proceedings, Ms Richards admitted making "catastrophic mistakes" at the birth.
I would like to offer our sincerest sympathies and apologies to Noah’s family, who we continue to support in any way we can. We are deeply sorry for what happened to Noah and Mrs Tyler, and this case has made us even more determined to constantly review and improve our services to ensure we provide the excellent care for mums and their babies that they have a right to expect.
We would like to reassure the public that we have thoroughly investigated what happened in this tragic case and have taken a number of clear and decisive actions, including dismissing the midwife involved.
