Both
are perfectly correct and sound perfectly natural in this example,
so use either or both. Generally speaking, the participialclause, starting with -ing or -ed, is more
characteristic of written English, as it allows us to say the same
thing as a relative clause, starting with who,
which or that, but with fewer words.
Participial clauses are also frequently heard in radio and
TV news broadcasts (as well as newspaper articles and reports) as
they permit a lot of information to be compressed into a limited
amount of time. This is one reason why they are often difficult
for a learner of English to follow.
The
reporting of The Great Train Robber Ronnie Biggs’ arrival back in
the UK a couple of weeks ago as he stepped off the plane after 35
years on the run in Australia and Brazil was reported as follows:
"The only glimpse of Biggs, dressed in blue shirt and green
sweater, lasted only a few seconds. Lawyers acting for Biggs
have said they will seek a hearing before the Court of Appeal".
A
participial clause, starting with –e»å or past participle,
is used instead of a relative pronoun plus passive voice. Study
these further examples:
Food
sold (= which is sold) in this supermarket is of
the highest quality.
Anyone
found touching (= who is found ) these priceless exhibits
will be escorted out of the museum.
The tailback on the A34 caused ( = which was caused / which
had been caused) by the head-on collision stretched for
over 20 miles in both directions.
It
took the ambulances called ( = that were called / that
had been called) to the scene over half an hour to get
through.
A
participial clause, starting with -ing is used instead
of a relative pronoun plus active verb, continuous or simple.
The
train now arriving (= which is now arriving) at platform
1 is the 6.36 from Newcastle.
There
are delays for people travelling to work (= who are travelling
to work) on Southern Region trains this morning.
Anyone
touching (= who touches ) these priceless exhibits
will be escorted out of the museum.
The police impounded all the vehicles belonging to (= which
belonged to) his brother.
The boy driving (= who was driving) the BMW was
underage, unlicensed and over the limit.
Note
that when we are talking about a single completed action in a defining
relative clause, we cannot use an active participle:
The
girl who fell down the cliff broke her leg.
(NOT: The girl falling down cliff…)
