The number of police officers on patrol around Broad Street in Birmingham and other city centre areas has been stepped up after a spate of needle attacks on women.
Five women have been stabbed with needles while on nights out over the past 18 months.
Supt Danny Long, from Birmingham Police, said he had stepped up patrols in a bid to reassure people visiting the city centre - and urged anyone who notices anything unusual to contact police.
This is an unusual offence which will understandably cause some concern and we are working extremely hard to find the person responsible.
We have increased the number of officers on patrol in Broad Street and around the city centre, particularly since the attack earlier this month, and are working closely with street wardens, street pastors, licensees, door staff and clubbers themselves to keep people safe.
Birmingham remains one of the safest cities in the UK in which to enjoy a night out but if anyone sees any suspicious activity, I would encourage them to report it to police immediately.
