Are Purple Pills Connected To Schoolboy's Illness?
Police are investigating whether purple pills found in Fife are connected to a case in which a teenage boy fell ill.
The 14-year-old was taken to Victoria Hospital in Kirkcaldy on March 21 after becoming unwell.
A day later, police recovered unidentified purple tablets at an address in the town which they say were bought online.
They are investigating to determine if the pills and the boy's illness are linked.
A Police Scotland spokesman said: "Police in Fife are investigating after a quantity of tablets were discovered at an address in Kirkcaldy on Wednesday.
"A 14-year-old boy had taken ill on Tuesday March 21. He was taken to the Victoria Hospital and discharged after treatment.
"The tablets, which were purchased online, are small, round and purple-coloured pills, and are yet to be identified.
"Anyone who thinks they have taken one of these is advised to seek immediate medical attention.
"Inquiries are ongoing to establish if the discovery of these pills and the boy's illness are linked.
"If you have further information about these tablets, please contact Police Scotland.''
A police watchdog probe was launched after the remains of the 52-year-old were found in a house in Dumfries in February last year.
The accident happened at about 7.50pm on Thursday in Moodiesburn, North Lanarkshire.
More than 70 firefighters were needed to bring the blaze under control at Blochairn Fruit Market in the early hours of Thursday.
